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. Change-Id: I137169f4d653ee2b7d6df14d41e2babd0ae8d10c BUG: 1188184 Signed-off-by: Kaleb S. KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/9912 Tested-by: Gluster Build System <jenkins@build.gluster.com>
