Description

Handle the user name correctly when user name is used as default queue name in fair scheduler.
It will be better to remove the trailing and leading whitespace of the user name when we use user name as default queue name, otherwise it will be rejected by InvalidQueueNameException from QueueManager. I think it is reasonable to make this change, because we already did special handling for '.' in user name.
