Title: INT-2485 Orderly Shutdown

https://jira.springsource.org/browse/INT-2485

Initial commit - @ManagedOperation on IMBE

- can be invoked via JMX, , or getting a reference to
the IMBE from the application context.

INT-2485 Updates After Review Comments (JIRA)

* Shutdown Schedulers first, and wait for them
* Add a force parameter, which overrides thread pool shutdown options
* Shutdown Sources/Channels after all thread pools have stopped
* Mark other components as OrderlyShutdownCapable (e.g. JMS/AMQP Listener containers) and shut them down first
* Wait for remaining time to allow for quiescence

Also
* remove TimeUnit parameter (not JMX-friendly); time limit is now always milliseconds
* If thread pools don't stop in time limit, force them down.

INT-2485 Handle Self-Destruction

Add shutdown-executor to IMBE.

When the shutdown was called on a Spring-Managed thread, the shutdown
was not clean because we timed out waiting for the current thread to
terminate. After that, we force terminated other components.

Now, by providing a dedicated Executor for the shutdown process, it
is used for the shutdown instead of the current thread. This Executor
is *not* shutdown.

It is not necessary to provide an Executor if the stopActiveComponents()
method is called on some other thread that is not involved in the
shutdown.

Also adds executor name to logs, when available.

INT-2485 Polishing

Fix MBean object name collision when running all tests.

INT-2485 Enable TCP Shutdown

Make TCP connection factories 'OrderlyShutdownCapable' so
they are stopped before schedulers/executors in order for
them to release any executor threads they are holding.
