> MAPREDUCE-4427 added server side support for umanaged AM's. This tracks
> creating client side supporting pieces.
> The basic flow of the client is as follows
> 1) accepts a cmd line for the AM. Optional queue information etc.
> 2) negotiates an application id with the RM and submits the unmanaged AM.
> 3) waits for the AM to reach YarnApplicationState ACCEPTED
> 4) then launches the AM in a separate process via the cmd provided. It
> communicated application attempt id to the AM via env variable. Stdout and
> stderr is redirected to the clients streams respectively.
> 5) waits for the AM process to exit and RM app to complete.
