Add support for working with multiple glusterfs volumes
This patch adds support for working with multiple glusterfs volumes for the GlusterFS native protocol driver. Since the semantics and mapping for native driver is different compared to GlusterFS NFS driver, this patch refactors the native driver as a standalone driver and fixes some flows to fit the native driver with the Manila share flows. A more recent version of glusterfs having SSL support is needed. Change-Id: I567c7602e97c9d55551baa29f121c05da2985007 Closes-Bug: #1368669
