          Issue Type: Bug
          Components: Mesos
            Reporter: Iulian Dragos


Add support inside the coarse-grained Mesos scheduler for dynamic allocation. 
It amounts to implementing two methods that allow scaling up and down the 
number of executors:

{code}
def doKillExecutors(executorIds: Seq[String])
def doRequestTotalExecutors(requestedTotal: Int)
{code}
