Description

The Fair Scheduler currently defaults the root queue's acl to empty and all other queues' acl to "*". Now that YARN-1258 enables configuring the root queue, we should reverse this. This will also bring the Fair Scheduler in line with the Capacity Scheduler.

We should also not trim the acl strings, which makes it impossible to only specify groups in an acl.
