no way to 'ssh controller' on kubernetes models

[John A Meinel]

We enabled support for 'juju ssh myapp/0' for kubernetes models.
However, the standard pattern of "juju ssh -m controller 0" to get to the controller doesn't work on K8s, because it doesn't "have machines" and requires that you ssh to a unit. But there isn't a unit here.

This may be easier once we model controllers as apps, but since that still isn't present in 2.9 we should have some sort of workaround. (And you can't use the machine trick of deploying something 'to the same machine' because k8s doesn't allow that, either.)
