cinder: enable glusterfs backend

This patch adds glusterfs backend into multi-backend cinder
support (total of lvm-iscsi, nfs, and glusterfs).  This including
changing cinder.conf, creating missing glusterfs_shares config file,
and adding glusterfs-client into compute/controller node and
gluster-server into controller node.

Also meta-filesystems is included to pickup fuse filesytem which
is needed by glusterfs.
