      Description

      The AM should be able to exec >1 process in a container, rather than have the NM automatically release the container when the single process exits.

      This would let an AM restart a process on the same container repeatedly, which for HBase would offer locality on a restarted region server.

      We may also want the ability to exec multiple processes in parallel, so that something could be run in the container while a long-lived process was already running. This can be useful in monitoring and reconfiguring the long-lived process, as well as shutting it down.
