Use DeadLetterPublishingRecoverer from Spring Kafka instead of custom DLQ components in the binder.
Remove code that is no longer needed for DLQ purposes.
In Kafka Streams, always set group to application id if the user doesn't set an explicit group.

then look for a header mapper bean with the name kafkaHeaderMapper.

When StreamListener based processors used in Kafka Streams
applications, it is not possible to register state store beans
using StateStoreBuilder. This is allowed in the functional model.
This method of providing custom state stores is desired as this
gives the user more flexibility in configuring Serde's and other
properties on the state store. Adding this feature to StreamListner
based Kafka Streams processors.
Adding test to verify.
Adding docs.
Resolves#676
Fixing an issue that causes a race condition when multiple functions
are present in a Kafka Streams application by isolating the responsible
proxy factory per function and not shared.
When multiple Kafka Streams functions are present in an application,
it should be possible to set the application id per function.
When an application provides a bean of type Serde, then the binder
should try to introspect that bean to see if it can be matched for
any inbound or outbound serialization.
Adding tests to verify the changes.
Adding docs.
Resolves#734, #735, #736
During application startup, there are cases when state stores
might take longer time to initialize. The call to find the
state store in the binder (InteractiveQueryService) will fail in
those situations. Providing a basic retry mechanism using which
applicaitons can opt-in for this retry.
Adding properties for retrying state store at the binder level.
Adding docs.
Polishing.

It appears we have refactored to rename the class from `KStreamProcessor` to `KafkaStreamsProcessor` [see a5344655cb (diff-4a8582ee2d07e268f77a89c0633e42f5)], but the docs weren't updated. This commit does exactly that.
