Run a Scenario when inMemory parameter is True

A REST request is made to the GMUS to run a Scenario with the inMemory parameter is set to true.  When inMemory is true, the following set up steps are executed:

  1. All Receivers associated with the Domain will be removed.
  2. The GenRocket SimpleMapReceiver is added to the Domain so it can produce the data in memory.

After the data is generated in memory it is passed back to the calling client as JSON.  

Important Note: When data is being generated in memory, loopCounts should be kept with a limited range the will not cause a Memory Heap exception.  For example, running a given GenRocket Scenario, that generates 1,000,000 rows of data to a given GenRocket Receiver, when inMemory = false, will not cause a memory issue since the GenRocket Engine will only generate one row of data in memory at any given time.  However, if inMemory = true or both, the GenRocket Engine will keep each row in memory until the Scenario completes its run; thus, a Memory Heap exception will occur if the system does not have enough memory; also the JSON response payload may be really huge and could cause issues for the response client.  A reasonable loopCount limit, when inMemory = true, might be 10,000.
