SAMZA-1359: Handle phantom container notifications cleanly during an RM
fail-over
1. Improved our container handling logic to be resilient to phantom
notifications.
2. Added a new metric to Samza's ContainerProcessManager module that tracks
the number of such invalid notifications.
3. Add a couple of tests that simulate this exact scenario above that we
encountered during the cluster upgrade. (container starts -> container fails ->
legitimate notification for the failure - container re-start -> RM fail-over ->
phantom notification with a different exit code)
4. As an aside, there are a whole bunch of tests in ContainerProcessManager
that rely on Thread.sleep to ensure that threads get to run in a certain order.
Removed this non-determinism and made them predictable.
