With this update, a single process can be used to host multiple bricks of a Gluster node. This leads to better volume density as the memory footprint of Gluster volume reduces.

Description of problem:
Enable brick multiplexing in rhgs container which enables high number of volume support in glusterd.
Test that 600 - 700 PVs (a mix of RWM + RWO) can be created per cluster with the RHGS 3.3 container because of resource consumption improvements enabled by brick multiplexing. The nodes must have adequate resource for the RHGS container.
The main feature that enables this capability will be delivered by the RHGS 3.3 release.
