GH-3446: Stream support in the MessageGroupStore

Browse Source 
Fixes https://github.com/spring-projects/spring-integration/issues/3446

* For better resources utilization provide a `Stream<Message<?>>` API
on the `MessageGroupStore`, `MessageGroup` and `MessageGroupQueue`
* Use this API in the `DelayHandler` when it reschedules persisted messages
