    Description

      Currently each AbstractService has a dispatcher, but the dispatcher is not named. Logs from dispatcher is mixed, which is quite hard to debug any hang issues. I suggest

      1. Make it possible to name AsyncDispatcher & its thread (partially done in YARN-6015)
      2. Mention the AsyncDispatcher name in all its logs
