Unless anyone objects, or has a better spelling, I will be adding a command
to do this:

    juju purge-controller <controller-name>

The command will require a "-y" or prompt for confirmation, like
kill-controller. It will not attempt to destroy the controller, it will
just remove the details of it from the client.

(Alternative suggestion for spelling: "juju forget-controller".
Purge-controller may suggest that we're purging a controller of its
contents, rather than purging the controller from the client?)

Cheers,
Andrew
