Xing Yang 2c3169e55e CLI: Non-disruptive backup
This is the CLI change required to support non-disruptive backup
for volumes in 'in-use' status. A force flag is added to the create
backup CLI. The force flag needs to be True when backing up an
'in-use' volume. By default it is False and it is not needed when
backing up an 'available' volume.

The Cinder server side change is merged:
