GEODE-681: Measuring event queue size without using the stat for gfsh

The eventQueueSize stat has issues with concurrent events during start
and stop that are leading it to be inaccurate. To make gfsh and jmx
correct,  measuring the queue size directly from the underlying region
size.

Adding unit tests for the size methods.

> The gateway sender maintains a stat that tracks the number of queued events in there region. 
> It does so by reading the number of events in the region after creating the queue and incrementing the stat by that number, and by having listeners on the region that also update the stat when entries are added or removed.
> Unfortunately, that approach can result in incorrect values for the stat because events can be double counted by the listener and the code that reads the size of the region.
