HIVE-8424 : Support fair scheduler user queue mapping in non-impersonation mode

Under non-impersonation mode, all MR jobs run as the hive system user. 
The default scheduler queue mapping is one queue per user. This is problematic
for users who use the queues to regulate and track their MR resource usage.

This patch uses the Yarn API to set the fair scheduler queue mapping for
the current user, if impersonation is turned off.
