Some of the loop control variables are global. This as expected has lead to corruption of their values, and produced undesired results. Fix this issue by setting the scope of these variables to local. Closes Bug: #1523348 Change-Id: I0f5676c5a0b97d3e027a1e7677b4b5a21470913b

- To install Glusterfs (client and server) packages
- By default all Gluster-[Glance|Nova|Cinder|Manila] integrations disabled. Look at "How to use" section, to know how to enable.
- Configures Glusterfs as a backend for Glance, Nova, Cinder and Manila as per localrc configuration
- Creates Gluster volumes to provide them as storage to Glance, Nova, Cinder or Manila
