Add image re/deactivate commands

This change allows admins to deactivate and reactivate their
images. Currently this has to be done with the REST api or the
glanceclient.

This change introduces `--deactivate` and `--activate` for the `image
set` command.

This requires glanceclient 1.2.0. Which got bumped here:
