Reduce RM app memory footprint once app has completed

      Description

      The ResourceManager holds onto a configurable number of completed applications (yarn.resource.max-completed-applications, defaults to 10000), and the memory footprint of these completed applications can be significant. For example, the submissionContext in RMAppImpl contains references to protocolbuffer objects and other items that probably aren't necessary to keep around once the application has completed. We could significantly reduce the memory footprint of the RM by releasing objects that are no longer necessary once an application completes.
