Should blacklist charm names finishing with names Juju uses

[howbazaar]

In particular relating to k8s charms, we have "app-operator", when deploying "app". Since the app name defaults to the charm name, we don't really want to allow a charm to be called "foo-operator" or we'll end up with a "foo-operator-operator".

[howbazaar]

Likely to be more than just "operator" suffix, but this issue can track the names as we get them.

I'd propose that you don't modify the application name to append a type to it.

Please could you make this into a proper proposal with a fuller rationale so we can discuss things there?
