             Fix For: 2.4.0


Fix the logic of size calculation while dealing with multi-level YARN queue for LLAP config
calculations. 
- Earlier, were not taking into account the percentage capacity allocated for each parent
queue of which the leaf queue is part of. 
- Added fix fir it.  

Added validation check for 'hive.server2.tez.sessions.per.default.queue'.
- If 'hive.server2.tez.sessions.per.default.queue' (tez session) are consuming more than 50%
of available capacity of LLAP queue, validation check is done.
