  - Full sleep wait change for PFC watchdog (sonic-net#465)
    
    * Sleep wait change for pfc watchdog, which still has plugins in place so
    isEmpty() always returns true.
    
    When issuing 'pfcwd stop' cli to stop PFC watchdog, it only clears the counter id list for physical ports under the hood, leaving lua script plugins still installed and ieEmpty() returns false.
    
    So even when PFC watchdog is stopped, the flex counter thread would wake up every 200 ms.

    This PR is to address the above observation:
    
    Fine granularize the isEmpty() to two functions---isIdsEmpty() and isPluginsEmpty(), and use the emptiness check of the counter id list, isIdsEmpty(), as the criteria for full sleep wait. This approach is generally valid because current flex counter use cases would have the presence of non-empty counter id list to be meaningful, followed by an optional execution of the Lua script plugins if they are installed.
