URL Cleanup

This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

# Fixed URLs

## Fixed Success
These URLs were switched to an https URL with a 2xx status. While the status was successful, your review is still recommended.

* [ ] http://repo.spring.io/libs-milestone-local with 2 occurrences migrated to:

-== Spring Cloud Stream Sample Applications
+== Samples
 
-This repository contains a collection of applications written using Spring Cloud Stream. All the applications are self contained.
-They can be run against either Kafka or RabbitMQ middleware technologies.
-You have the option of running the samples against local or Docker containerized versions of Kafka and Rabbit.
-For convenience, `docker-compose.yml` files are provided as part of each application wherever it is applicable.
-For this reason, Docker Compose is required and it’s recommended to use the https://docs.docker.com/compose/install/[latest version].
-These compose files bring up the middleware (kafka or Rabbit) and other necessary components for running each app.
-If you bring up Kafka or RabbitMQ in Docker containers, please make sure that you bring them down while in the same sample directory.
-You can read the README that is part of each sample and follow along the instructions to run them.
+There are several samples, all running on the RabbitMQ transport (so you need RabbitMQ running locally to test them).
 
-You can build the entire samples by going to the root of the repository and then do: `./mvnw clean package`
-However, the recommended approach to build them is to pick the sample that you are interested in and go to that particular app and follow the instructions there in the README for that app. 
+To build the samples do:
 
-=== Following is the list of various sample applications provided
+```
+   ./mvnw clean build
+```
 
-==== Source samples
+NOTE: The main set of samples are "vanilla" in the sense that they are not deployable as XD modules by the current generation (1.x) of XD. You can still interact with an XD system using the appropriate naming convention for input and output channel names (`<stream>.<index>` format).
 
-* Source with dynamic destinations (Kafka and Rabbit)
+* `source` is a Java config version of the classic "timer" module from Spring XD. It has a "fixedDelay" option (in milliseconds) for the period between emitting messages.
 
-==== Processor samples
+* `sink` is a Java config version of the classic "log" module from Spring XD. It has no options (but some could easily be added), and just logs incoming messages at INFO level.
 
-* Basic StreamListener sample (Kafka and Rabbit)
-* Transformer sample (Kafka and Rabbit)
-* Reactive processor sample (Kafka and Rabbit)
-* Sensor average calculation using reactive patterns (Kafka and Rabbit)
+* `transform` is a simple pass through logging transformer (just logs the incoming message and passes it on).
 
-==== Multi IO sample
+* `double` is a combination of 2 modules defined locally (a source and a sink, so the whole app is self contained).
 
-* Sample with multiple input/output bindings (Kafka and Rabbit)
+* `multibinder` is a sample application that shows how an application could use multiple binders. In this case, the processor's input/output channels connect to different brokers using their own binder configurations.
 
-==== Multi Binder samples
+* `multibinder-differentsystems` shows how an application could use same binder implementation but different configurations for its channels. In this case, a processor's input/output channels connect to same binder implementation but with two separate broker configurations.
 
-* Multi binder - Input with Kafka and output with Rabbit
-* Multi binder - Same binder type but different clusters (Kafka only, but can be extended for Rabbit as well)
+If you run the source and the sink and point them at the same redis instance (e.g. do nothing to get the one on localhost, or the one they are both bound to as a service on Cloud Foundry) then they will form a "stream" and start talking to each other. All the samples have friendly JMX and Actuator endpoints for inspecting what is going on in the system.
 
-==== Kinesis
-
-* Kinesis produce consume sample
-
-==== Kafka Streams samples
-
-A collection of various applications in stream processing using Spring Cloud Stream support for Kafka Streams binding.
-
-* Kafka Streams word count
-* Kafka Streams branching
-* Kafka Streams DLQ
-* Kafka Streams aggregation
-* Kafka Streams Interactive query basic
-* Kafka Streams Interactive query advanced
-* Kafka Streams product tracker
-* Kafka Streams KTable join
-* Kafka Streams and normal Kafka binder together
-
-==== Testing samples
-
-* Sample with embedded Kafka
-* General testing patterns in Spring Cloud Stream
-
-==== Function-based stream app samples
-
-Contains samples using the re-architected stream-applications and base functions included in https://github.com/spring-cloud/stream-applications.

-= Thumbnail Stream Sample
-
-== Run with docker-compose
-
-If you have docker installed and running, this is the easiest way to run this sample.
-
-=== Build the link:image-thumbnail-sink[] 
-
-Build the docker image to register with the local Docker daemon. 
-
-```
-cd image-thumbnail-sink
-./mvnw clean package jib:dockerBuild
-```
-=== Create input and output directories `images` and `thumbnails`.
-These names are referenced in link:docker-compose-apps.yml[]
-
-```
-cd image-thumbnail-stream-sample
-mkdir images thumbnails
-```
-
-=== Start the containers
-
-```
-docker-compose -f docker-compose-kafka.yml -f docker-compose-apps.yml up
-```
-
-Proceed to xref:Create_Some_Data[Create Some Data]
-
-== Run standalone
-We will use this sink in a streaming application that reads a text file containing image URLs and create a thumbnail file for each image: `file-source | http-request-processor | image-thumbnail-sink`
-
-=== Download the pre-packaged Source and Processor applications:

-=== Start a Kafka message broker
-
-If you have Docker installed, you can start Kafka with
-```
-docker-compose up -f docker-compose-kafka.yml 
-```
-
-Or install and run Kafka on your local machine. 
-If you are using a remote Kafka cluster, set the property `--spring.cloud.stream.kafka.brokers=kafka_host1,...` to a comma-delimited list of host addresses on each of the following apps.
-
-=== Create input and output directories 
-Named `images` and `thumbnails` in this example.
-
-=== Start the sink
-Build the link:image-thumbnail-sink[], if you haven't already done it.
-Then open a terminal window in `image-thumbnail-sink` and run:
-
-```
-java -jar target/image-thumbnail-sink-0.0.1-SNAPSHOT.jar --file.consumer.directory=$(PWD)/thumbnails --spring.cloud.stream.bindings.input.destination=thumbnail --server.port=0
-```
-
-
-=== Start the source and processor
-
-In separate terminal sessions run the processor and the source:
-
-```
-java -jar http-request-processor-kafka-3.0.0-SNAPSHOT.jar --http.request.url-expression=payload --http.request.expected-response-type=byte[] --http.request.maximum-buffer-size=2097152 --spring.cloud.stream.bindings.input.destination=image --spring.cloud.stream.bindings.output.destination=thumbnail --spring.kafka.producer.properties.max.request.size=2097152 --server.port=0
-```
-
-```
-java -jar file-source-kafka-3.0.0-SNAPSHOT.jar --file.consumer.mode=lines --file.supplier.directory=$(PWD)/images --spring.cloud.stream.bindings.output.destination=image --server.port=0
-```
-[[Create_Some_Data]]
-=== Create some data
-
-Using your favorite text editor, create a file in the `images` directory containing some URLs:
-
-```
-https://i.imgur.com/FQtKSuv.jpeg
-https://i.imgur.com/4Cndaul.jpeg
-https://i.imgur.com/FCPLS42.jpeg
-https://i.imgur.com/DhzHsz8.jpg
-https://i.imgur.com/G7t1ZZl.jpg
-```
-
-You should see the thumbnail files in the `thumbnails` directory.

-= Thumbnail Sink
-
-A Spring Cloud Stream Sink which composes thumbnailProcessor|filenameEnricher|fileConsumer to create thumbnails and write to a file.
-
-This app registers the link:../image-thumbnail-processor/src/main/java/io/spring/example/image/thumbnail/processor/ThumbnailProcessor.java[ThumbnailProcessor] as a Spring bean and uses the standard https://github.com/spring-cloud/stream-applications/tree/master/functions/consumer/file-consumer[fileConsumer] to write files.
-It implements a link:src/main/java/io/spring/example/image/thumbnail/sink/ThumbnailSinkApplication.java[filenameEnricher] function, which generates filenames as
-`thumbnail-%d.jpg`, incrementing the index on each execution, supplied to the fileConsumer in the `filename` message header.
-See Also link:src/main/resources/application.properties[application.properties].

-== What is this app?
-
-This is an example of a Spring Cloud Stream demonstrating the processing of record batches.
-
-The application simply upper-cases the input records and sends them to another topic.
-
-=== Running the app:
-
-Go to the root of the repository and do:
-
-`docker-compose up -d` (if you don't already have a Kafka broker running locally).
-
-`./mvnw clean package`
-
-`java -jar target/kafka-batch-sample-0.0.1-SNAPSHOT.jar `
-
-There is a simple `@KafkaListener` method to display the records sent to the output topic.
-
-When run with `java -jar target/kafka-batch-sample-0.0.1-SNAPSHOT.jar --spring.profiles.active=transactional` the listener will suspend with
-
-`Hit Enter to exit the listener and commit transaction`.
-
-Pressing the enter key allows the listener to exit and the transaction will commit.
-
-Only then will you see the output from the `@KafkaListener` because its consumer is configured with `isolation.level: read_committed`.

-== What is this app?
-
-This is an example using Spring Cloud Stream to model a subset of a purchasing system. This e2e project showcases the following
-features:
-
-* Avro messaging
-* Confluent Schema Registry
-* Event-carried state transfer pattern
-* KStream processing with a join operation
-
-=== Running the app:
-
-Start the Confluent Platform:
-
-```
-git clone https://github.com/confluentinc/cp-docker-images
-cd cp-docker-images
-git checkout 5.2.1-post
-cd examples/cp-all-in-one/
-docker-compose up -d --build
-```
-
-Go to the root of the sample project and do:
-
-`./mvnw clean package`
-
-`java -jar customer-service/target/customer-service-0.0.1-SNAPSHOT.jar`
-
-`java -jar order-service/target/order-service-0.0.1-SNAPSHOT.jar`
-
-`java -jar shipping-service/target/shipping-service-0.0.1-SNAPSHOT.jar`
-
-
-Start two https://github.com/edenhill/kafkacat[kafkacat] processes to examine topic information:
-
-```
-kafkacat -b localhost:9092 -t customer -C \
-  -f '\nKey (%K bytes): %k
-  Value (%S bytes): %s
-  Timestamp: %T
-  Partition: %p
-  Offset: %o
-  Headers: %h\n'
-```
-
-
-```
-kafkacat -b localhost:9092 -t order -C \
-  -f '\nKey (%K bytes): %k
-  Value (%S bytes): %s
-  Timestamp: %T
-  Partition: %p
-  Offset: %o
-  Headers: %h\n'
-```
-
-Create a customer:
-
-`curl -X POST -H "content-type: application/json" http://localhost:8084/customers -d '{"id":1,"name":"John Doe","address":"Elm Street"}'`
-
-Create an order for that customer:
-
-`curl -X POST http://localhost:8085/orders -H "content-type: application/json" -d '{"id":1,"productId":100,"customerId":1}'`
-
-Check the kafkacat output to verify that there is a record in the customer topic, and two in the order topic, corresponding
-to the OrderCreatedEvent from customer-service and the OrderShippedEvent from shipping-service.
-
-Customer topic kafkacat output:
-
-```
-Key (4 bytes):
-  Value (26 bytes): John DoeElm Street
-  Timestamp: 1561153134430
-  Partition: 0
-  Offset: 0
-  Headers:
-
-```
-
-Order topic kafkacat output:
-
-```
-Key (4 bytes):
-  Value (9 bytes): ?
-  Timestamp: 1561153313512
-  Partition: 0
-  Offset: 0
-  Headers:
-
-Key (4 bytes):
-  Value (28 bytes): ?John DoeElm Street
-  Timestamp: 1561153313512
-  Partition: 0
-  Offset: 1
-  Headers:
