KonkService and Konk have mismatched scope

[drewwells]

If you install Konk with scope=cluster and KonkService with konk.scope=namespace, the cluster does not start in obscure ways. We need to surface an error when the scope is mismatched.

One idea is instead of setting Konk values like scope in KonkService, we could read them directly from the named Konk CR.
