Revert "packaging: (ganesha) remove glusterfs-ganesha subpackage and related files"

Until 3.12, glusterd had an option to setup HA cluster for nfs-ganesha using pacemaker
and corosync. But later infavour of "Storhaug" Project, this functionality was removed
from the codebase. Since there is not much development happening towards storhaug,
it better to keep back old working HA solution for nfs-ganesha with bit improvements.

Planned improvements :

* add an option in nfs-ganesha enable to set ganesha without HA.

* Handle usage of export id's properly in the scripts.
