Include git describe --always --dirty in git info

Please include git describe --always --dirty in the git repository information, we find it's most informative. IMO when it's not dirty, its a better tag as well, though you do end up with a lot of them on your machine.

FWIW- the Aggie Experts rules are :

• --env=dev is always tagged :dirty
• --env=sandbox,clean can't be dirty and are always localhost/aggie-expert and always built locally
• you can only save tagged images to the registry.
