Currently, KafkaBinderHealthIndicator is not customizable and included by default
when Spring Boot actuator is on the classpath. Fix this by allowing the application
to provide a custom implementation. A new marker interface called KafkaBinderHealth
can be used by the applicaiton to provide a custom HealthIndicator implementation, in
which case, the binder's default implementation will be excluded.
Tests and docs changes.

InteractiveQueryService methods for finding the host info for Kafka Streams
currently throw exceptions if the underlying KafkaStreams are not ready yet.
Introduce a retry mechanism so that the users can control the behaviour of
these methods by providing the following properties.
spring.cloud.stream.kafka.streams.binder.stateStoreRetry.maxAttempts (default 1)
spring.cloud.stream.kafka.streams.binder.stateStoreRetry.backoffPeriod (default 1000 ms).

Allow health checks on KafkaStreams processors that are currently stopped through
actuator bindings endpoint. Add this only as an opt-in feature through a new binder
level property - includeStoppedProcessorsForHealthCheck which is false by default
to preserve the current health indicator behavior.

This PR safe guards state store instances in case there are multiple KafkaStreams
instances present that have distinct application IDs but share State Store Names.
Change is backwards compatible: In case no KafkaStreams association of the thread
can be found, all local state stores are queried as before.
In case an associated KafkaStreams Instance is found, but required StateStore is
not found in this instance, a warning is issued but backwards compatibility is
preserved by looking up all state stores.
Store within KafkaStreams instance of thread is preferred over "foreign" store with same name.
Warning is issued if requested store is not found within KafkaStreams instance of thread.
The main benefit here is to get rid of randomly selecting stores across all KafkaStreams instances
in case a store is contained within multiple streams instances with same name.
