SAMZA-1282: Spinning up more containers than number of tasks.
Changes
* Stop streamProcessor in onNewJobModelAvailable eventHandler(instead of
onNewJobModelConfirmed
eventHandler) when it's not part of the group and prevent it from joining
the barrier.
* When numContainerIds > numTaskModels, generate JobModel by choosing
lexicographically
least `x` containerIds(where x = numTaskModels).
* Added unit and integration tests in appropriate classes to verify the
expected behavior.
