juju: Make kubernetes-master status handling more robust
**What this PR does / why we need it**:
This fixes a charm hook failure that can occur after restarting kubernetes-master units in Juju-based Kubernetes deployments.
This should also hopefully make our status handling in kubernetes-master more robust in general, by making sure all of our `blocked`, `waiting`, and `active` status messages are handled in one place, on hook exit.

Clearing out the client-ca-file option
**What this PR does / why we need it**:
kubernetes-master charm wouldn't clear the ca-client-file snap setting. We haven't used it for a while, but since it wasn't clearing it out any old deploys that updated would still have it set. This change will start clearing it.
