Add volume backup import/export commands

This adds commands to import and export volume backup records so they
can be imported and restored on other Cinder instances or to the
original instance if the service or database has been lost and had to be
rebuilt.

I know this is a commonly used process by some users, so it would be
good to have this functionality in osc so they do not have to switch
clients.

More details about the export and import process can be found here:

https://docs.openstack.org/cinder/latest/admin/blockstorage-volume-backups-export-import.html
