Provide an ability to refresh queue configuration without restart.

Key: MAPREDUCE-893
URL: https://issues.apache.org/jira/browse/MAPREDUCE-893
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: jobtracker
Reporter: Hemanth Yamijala
While administering a cluster using multiple queues, administrators feel a need
to refresh queue properties on the fly without needing to restart the
JobTracker. This is partially supported for some properties such as queue ACLs
(HADOOP-5396) and state (HADOOP-5913). The idea is to extend the facility to
refresh other queue properties as well, including scheduler properties.
