BD Backend: Volume creation support
A new parameter type is added to volume create command. To use BD xlator
one has to specify following argument in addition to normal volume
create
device vg brick:<VG-NAME>
for example,
$ gluster volume create lv_volume device vg host:/vg1
Changes from previous version
* New type 'backend' added to volinfo structure to differentiate between
posix and bd xlator
* Most of the volume related commands are updated to handle BD xlator,
like add-brick, heal-brick etc refuse to work when volume is BD xlator
type
* Only one VG (ie brick) can be specified for BD xlator during volume
creation
* volume info shows VG info if its of type BD xlator
BUG: 805138
