snapshot : copying nfs-ganesha export file
While taking snapshot, the export file used by the volume should
copy to snap directory. So that when restore of snapshot happens,
the volume can retain all its configuration for exporting via
nfs-ganesha. The export file is stored at "/etc/ganesha/export" in
the following format "export.<volname>.conf"
The fix handles given cases in the following manner :
case a: The nfs-ganesha(global) is ON during snapshot and restore.
i.) Volume was exported during snapshot. When we restore snapshot,
then volume should be exported back with old configuration file.
ii.) Volume was unexported during snapshot. When we restore snapshot,
then volume should unexported again.
case b: The nfs-ganesha is ON during snapshot and OFF during restore
Volume was exported during snapshot. When we restore snapshot, the
conf will be copied to corresponding location and if nfs-ganesha enabled
again, then volume will be exported.
For the clones, export conf file will created in /etc/ganesha/export and then
export it via ganesha.
