Subject: NFS-Ganesha : Unexport fails after S31ganesha-start script is run

The dbus-send script extracts the export ID from the export config
file. It expects the export ID to be written in a particular format.
The post-phase hook-script created the export file in a different
format, and the dbus-send never gets the correct export ID because
of this. Fixing the issue by replacing the write_conf function in the
S31ganesha-start hook-script. Also, NFS-Ganesha service stops when
dbus signal is sent more than once on the same export. Consecutive
start/stop operations creates problems. Fixing all the issues at once.

Change-Id: I1306c68e2bc9abd91be1b7f1558c93060cc9c98d
