Subject: [PATCH 230/235] 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
