Description

Also along the lines of MESOS-938, replaceTask would one of a couple of primitives needed to support various task replacement and scaling scenarios. This replaceTask() version is significantly simpler than the first proposed one; it's only responsibility is to run a new task info on a running tasks resources.
The running task will be killed as usual, but the newly freed resources will never be announced and the new task will run on them instead.
