--------------------------------

update the patch to fix TestFairScheduler, adding drainEvents after a node is registered.
not using a rm.dispatcher.handle() for most TestFairScheduler not using this way.

> seen many test failures related to RMApp/RMAppattempt comes to some state but some event
are not processed in rm event queue or scheduler event queue, cause test failure, seems we
could implicitly invokes drainEvents(should also drain sheduler event) in some mockRM method
like waitForState
