Add MessageHistory header property [INT-87]

[spring-operator]

Mark Fisher opened INT-87 and commented

The MessageHistory will keep track of the components and channels through which a Message has passed. This is primarily useful for debugging and monitoring purposes, but may also be useful for handling ErrorMessages (attempt to redeliver to a channel).

Moving to M4 since we will likely be making changes to the MessageHandlerChain that will reduce the amount of newly created messages (e.g. transformation may not require a new message if the message payload becomes mutable). These changes should also simplify and provide more value to the MessageHistory.

Moving to 1.1

Resolving this particular issue since the base support has been added (the MessageHistory object, its initialization within a header, and its access from AbstractMessageChannel and AbstractMessageHandler).

#4861 and #4952 adequately describe the known limitations that we still need to address.
