Adds a new command to upgrade containerised services on the seed:

kayobe seed service upgrade

This is largely the same as the deploy command, since there is no
kolla-ansible bifrost-upgrade command yet.

A limitation in Bifrost requires us to remove IPA images before
upgrading the bifrost container.
