Yong Tang 6c5c34d50d Add --force in docker volume rm to fix out-of-band volume driver deletion
This fix tries to address the issue in raised #23367 where an out-of-band
volume driver deletion leaves some data in docker. This prevent the
reuse of deleted volume names (by out-of-band volume driver like flocker).

This fix adds a `--force` field in `docker volume rm` to forcefully purge
the data of the volume that has already been deleted.

Related documentations have been updated.

This fix is tested manually with flocker, as is specified in #23367.
An integration test has also been added for the scenario described.

This fix fixes #23367.
