      Description

      To reproduce

      1. start cdap-master
      2. start a long running program (flow or service)
      3. restart cdap-master

      After restart, hitting the UI couple times will make REST call to master unresponsive. The reason is there is a deadlock inside the DistributedProgramRuntimeService.
