Introducing the capability of routing records based on
event types. If a header in the incoming record contains
the event type set on the binding, then the function
associated with that binding gets invoked.
Adding test/docs.
Resolves https://github.com/spring-cloud/spring-cloud-stream-binder-kafka/issues/1003
Fixed typo `springc` to `spring` in two lines:
`spring.cloud.stream.function.bindings.process-in-0=users`
`spring.cloud.stream.function.bindings.process-in-0=regions`
Add a new producer extended property for allowNonTransactional.
When set to true, records published to this output binding will
not be run in a transaction, unless one is already in process.
By default, all ouput bindings associated with a transactional
binder publishes in a new transaction. This new property can be
used to override this behavior.

* Copy cert files from classpath to file-system
If `ssl.truststore.location` and `ssl.keystore.location` are
provided as classpath resources, convert them to absolute paths
on the filesystem. This is because of a restriction in the Kafka client
in which it does not allow certificates to be read from the classpath.
See these issues for more details:
https://issues.apache.org/jira/browse/KAFKA-7685https://cwiki.apache.org/confluence/display/KAFKA/KIP-398%3A+Support+reading+trust+store+from+classpath
This commit allows the Spring Cloud Stream application to provide the
cert files as classpath: reosources, but the binder internally move
them to a locations on the local filesystem and then use that absolute
path as the value for cert locations. Adding properties for optional paths
to move the files to. If no values are provided for these properties,
then use the system's /tmp directory.
Adding tests and docs.

The property spring.cloud.stream.binder.configuration.num.stream.threads does not work and is silently ignored.
The property spring.cloud.stream.kafka.streams.binder.configuration.num.stream.threads works fine and is already covered by tests at MultipleFunctionsInSameAppTests#125

* Allow retries in Kafka Streams binder
Provide applications the capability to retry critical sections of the
business logic. This is accomplished through a new API using which
critical path can be wrapped inside a Callable.
Adding tests and docs.
Resolves https://github.com/spring-cloud/spring-cloud-stream-binder-kafka/issues/945
* Reworking the PR
Remove the binder API that was added before for retrying.
Reuse binding provided RetryTemplate.

* Cleanup
* Addressing PR review comments
* Fix typo
* Custom DLQ Destination Resolver
Allow applications to provide a custom DLQ destination resolver
implementaiton by providing a new interface DlqDestinationResolver
as part of binder's public contract. This interface is a BiFunction
extension using which the applications can provide more fine grained
control over where to route records in error.
Adding test to verify.
Adding docs.

* Customizing producer/consumer factories

customizers to perform advanced configuration on the producer
and consumer factories.

* Deprecate autoCommitOffset in favor or ackMode
Deprecate autoCommitOffset in favor of using a newly introduced consumer property ackMode.
If the consumer is not in batch mode and if ackEachRecord is enabled, then container
will use RECORD ackMode. Otherwise, use the provided ackMode using this property.
If none of these are true, then it will defer to the default setting of BATCH ackMode
set by the container.

* Fix health indicator to properly indicate partition failure
* Add new flag to control binder health indicator behavior
* Regardless of the consumer that is reading from a partition, if the binder
detects that a partition for the topic is without a leader, mark the binder
health as DOWN (if the flag is set to true).
* Remove synchronize block since only one thread executes the block
* Add Docs for the new binder flag
* Fix checkstyle issues
* Change default replication factor to -1
Binder now uses a default value of -1 for replication factor signaling the
broker to use defaults. Users who are on Kafka brokers older than 2.4,
need to set this to the previous default value of 1 used in the binder.
In either case, if there is an admin policy that requires replication factor > 1,
then that value must be used instead.

* Addressing PR review comments
* Kafka Streams metrics in the binder for Boot 2.2 users are streamlined to
reflect the Micrometer native support added with version 1.4.0 which is
available through Boot 2.3. While Boot 2.3 users will get this native support
from Micrometer, Boot 2.2 users will still rely on the custom implementation
in the binder. This commit aligns that custom implemenation more with
the native implementation.
* Disable the custom Kafka Streams metrics bean which is mentioned above
(KafkaStreamsBinderMetrics) when the application is on Boot 2.3, as this
implementation is only applicable for Boot 2.2.x.
* Update docs
