These patches add the `location` parameter in python-cinderclient's
`backup-create` command and in python-openstackclient's `volume backup
create` command to allow the optional specification of volume backup
locations.
The unit tests for both clients were updated accordingly.
Test Plan:
PASS - Build python-cinderclient package
PASS - Build python-openstackclient package
PASS - Verify that the `--location` parameter is available for use in
both clients when creating volume backups
