Clearly something changed in the dependencies and nothing that is required in the guests seems to need keystone client.

As a result

you see that keystone client isn't getting installed.

On the other hand, in a previous (passing) build you see that it is.

I have no idea what caused this to change but the fix is to get the client onto the guest. testing fix now.
