glusterd-ganesha : copy ganesha export configuration files during reboot
glusterd creates export conf file for ganesha using hook script during volume start and ganesha_manage_export() for volume set command. But this routine is not added in glusterd restart scenario. Consider the following case, in a three node cluster a volume got exported via ganesha while one of the node is offline(glusterd is not running). When the node comes back online, that volume is not exported on that node due to the above mentioned issue. Also I have removed unused variables from glusterd_handle_ganesha_op() For this patch to work pcs cluster should running on that be node.
