    [FLINK-8328] [flip6] Move Yarn ApplicationStatus polling out of YarnClusterClient
    
    Introduce YarnApplicationStatusMonitor which does the Yarn ApplicationStatus polling in
    the FlinkYarnSessionCli. This decouples the YarnClusterClient from the actual communication
    with Yarn and, thus, gives a better separation of concerns.
