INT-2214, INT-343, INT-2250 MessageHandler Advice

Browse Source 
Add general capability to advise just the handleRequestMessage
part of an AbstractReplyProducingMessageHandler.

This is to advise just the immediate operation, and not the
entire downstream flow.

Uses include:

* outbound gateway post processing
* adding retry behavior using spring-retry
* adding circuit breaker functionality

Initial commit for review.

Also need to advise simple message handlers (such as file
etc) to allow them to post-process file operations
with payload.delete(), payload.renameTo(...) etc.

INT-2250 Add Circuit Breaker Advice

INT-343 Add Retry Advice

Stateless and Stateful retry using spring-retry. Stateless
means the RetryTemplate performs the retries internally.
Stateful means the exception is thrown (e.g. to JMS container)
and the retry state is maintained by spring-retry.

INT-2215, INT-343, INT-2250 Refactoring

Factor out common abstract Advice class.

INT-2214 Catch Evaluation Expression Exceptions

If an onSuccess expression evaluation fails, add an
option so the user can decide whether such an exception is
caught, or propagated to the caller.
