    Description

      From discussion on YARN-1027, it makes sense to separate out services that are stateful and stateless. The stateless services can run perennially irrespective of whether the RM is in Active/Standby state, while the stateful services need to be started on transitionToActive() and completely shutdown on transitionToStandby().

      The external-facing stateless services should respond to the client/AM/NM requests depending on whether the RM is Active/Standby.
