Only storage backend for RBD (RADOS Block Device), FS and directory
have the resizeVol function, so only testing dir volume here.
Flags 'allocate' and 'shrik' are with bug:
https://bugzilla.redhat.com/show_bug.cgi?id=804516
they are not supported yet, so leave the case for later.
* using volume resize API with flag VIR_STORAGE_VOL_RESIZE_DELTA
* using volume info API to get volume info and check
* add dir volume resize conf
