> --> When Hive Server Interactive is turned ON:
> ===================================
>   Ambari creates OR "modifies 'llap' queue 'state and/or capacity' " based on below conditions:
>        -  if only 1 queue exists at root level and is 'default' queue and has 100% cap -> Creates 'llap' queue,  OR
>        -  if 2 queues exists at root level ('llap' and 'default') :
>            -> 'llap' queue state is STOPPED -> Modifies 'llap' queue state to RUNNING, adjusts capacity, OR
>            -> 'llap' queue state is RUNNING and 'llap_queue_capacity' prop != 'llap' queue current running capacity ->
>               Modifies 'llap' queue capacity to 'llap_queue_capacity'.
>               
> --> When Hive Server Interactive is turned OFF:
> ===================================
>       -   Checks and sees (1). If only two leaf queues exist at root level, namely: 'default' and 'llap',
>                   and (2). 'llap' is in RUNNING state.
>       - If yes, performs the following actions:   (1). 'llap' queue state set to STOPPED,
>                                                 (2). 'llap' queue capacity set to 0 %,
>                                                 (3). 'default' queue capacity set to 100 %
