NFS-Ganesha: Install scripts, config files, and resource agent scripts

Resubmitting after a gerrit bug bungled the merge of
http://review.gluster.org/9621 (was it really a gerrit bug?)

Scripts related to NFS-Ganesha are in extras/ganesha/scripts.
Config files are in extras/ganesha/config.
Resource Agent files are in extras/ganesha/ocf

Files are copied to appropriate locations.

+%description ganesha
+GlusterFS is a distributed file-system capable of scaling to several
+petabytes. It aggregates various storage bricks over Infiniband RDMA
+or TCP/IP interconnect into one large parallel network file
+system. GlusterFS is one of the most sophisticated file systems in
+terms of features and extensibility.  It borrows a powerful concept
+called Translators from GNU Hurd kernel. Much of the code in GlusterFS
+is in user space and easily manageable.
+
+This package provides the configuration and related files for using
+NFS-Ganesha as the NFS server using GlusterFS
