glusterd/ganesha : handle volume reset properly for ganesha options

The "gluster volume reset" should first unexport the volume and then delete
export configuration file. Also reset option is not applicable for ganesha.enable
if volume value is "all".
This patch also changes the name of create_export_config into manange_export_config
