glusterd: Mark vol as deleted by renaming voldir before cleaning up the store
PROBLEM: During 'volume delete', when glusterd fails to erase all information about a volume from the backend store (for instance because rmdir() failed on non-empty directories), not only does volume delete fail on that node, but also subsequent attempts to restart glusterd fail because the volume store is left in an inconsistent state. FIX: Rename the volume directory path to a new location <working-dir>/trash/<volume-id>.deleted, and then go on to clean up its contents. The volume is considered deleted once rename() succeeds, irrespective of whether the cleanup succeeds or not.
