    [STORM-1711] Kerberos principals gets mixed up while using storm-hive

    Storm-hive uses UserGroupInformation.loginUserFromKeytab which updates the 
static variable that stores current UGI. Modified HiveUtils.authenticate to use 
UserGroupInformation.loginUserFromKeytabAndReturnUGI() which returns the new 
UGI instead of modifying the current UGI.
