Description

As mentioned in MESOS-938, one way to support task replacement and scaling could be to split the responsibility into several smaller primitives for 1) reducing complexity 2) Make it easier to comprehend and 3) easier and incremental in implementation.

resizeTask() would be the primitive to either
1) Scale a running task's resources down
2) Scale a running task's resources up by using extra auxiliary offers.
