glusterd/ganesha : Move ganesha-ha.conf and ganesha.conf to shared storage

Currently all the ganesha related configuration files(ganesha.conf,
ganesha-ha.conf, export files, etc) is stored locally at /etc/ganesha
on a every node in ganesha cluster. Usually we end up in two issues by
doing so :
* difficult in modifiying ganesha related conf file
* diffciult to maintain consistency of conf file across ganesha cluster
To tackle this, we plan to move all the ganesha configuration to shared
storage. As a first step in this patch ganesha.conf and ganesha-ha.conf
move to shared storage. Here actual ganesha.conf will resides in shared
stoarge and symlinks will be created in /etc/ganesha when the option
"gluster nfs-ganesha enable" is executed and remove those during the
"disable" part.

Modified prerequisites to done before running globaloption:
	* enable shared storage
	* create nfs-ganesha folder in shared storage
	* create ganesha.conf and ganesha-ha.conf in it
