Update zake to requirements version

Zake has been updated in the global requirements
repository to be zake>=0.0.20, so in order for the
requirements bot to get its change through (without
updating hacking) we need to separate this change
out.

Add datastore version to backups

This fix adds datastore information to the backup APIs.
These API includes backup list, backup list by instance and
backup show.

Also this fix enhances backup-list to optionally receive a
datastore to filter the backups by.

The integration tests will fail until the update for the client
gets merged: https://review.openstack.org/#/c/90462/
