>     - Moved locks out of MasterProcedureScheduler#Queue. One Queue object is used for
each namespace/table, which aren't more than 100. So we don't complexity arising from all
functionalities being in one place. MasterProcedureLocking#Lock is the new locking class.
>     - Removed NamespaceQueue because it wasn't being used as Queue (add,peek,poll,etc
functions threw UnsupportedOperationException). It's was only used for locks on namespaces.
Now that locks have been moved out of Queue class, it's not needed anymore.
>     - Remoed RegionEvent which was there only for locking on regions. Tables/namespaces
used locking from Queue class and regions couldn't (there are no separate proc queue at region
level), hence the redundance. Now that locking is separate, we can use the same for regions
too.
>     - Removed QueueInterface class. No declarations, except one implementaion, which
makes the point of having an interface moot.
>     - Removed QueueImpl, which was the only concrete implementation of abstract Queue
class. Moved functions to Queue class itself to avoid unnecessary level in inheritance hierarchy.
>     - Removed ProcedureEventQueue class which was just a wrapper around ArrayDeque class.
>     - Encapsulated table priority related stuff in a single class.
>     - Removed some unused functions.
> *Perf using MasterProcedureSchedulerPerformanceEvaluation*
> 10 threads, 10M ops, 5 tables
> Without patch:
> 10 regions/table : #yield 584980, addBack time 4.1s, poll time 10s
> 1M regions/table: #yield 16, addBack time 5.9s, poll time 12.9s
> With patch:
> 10 regions/table : #yield 86413, addBack time 4.1s, poll time 8.2s
> 1M regions/table: #yield 9, addBack time 6s, poll time 13s
> *Memory footprint and CPU* (don't compare GC as that depends on life of objects which
will be much longer in real-world scenarios)
> Without patch
> !without-patch.png|width=800!
> With patch
> !with-patch.png|width=800!
