Yes, this is a huge commit.
The middleware allows you to customize the API groups of all of the
*.pinniped.dev API groups.
Some notes about other small things in this commit:
- We removed the internal/client package in favor of pkg/conciergeclient. The
two packages do basically the same thing. I don't think we use the former
anymore.
- We re-enabled cluster-scoped owner assertions in the integration tests.
This code was added in internal/ownerref. See a0546942 for when this
assertion was removed.
- Note: the middlware code is in charge of restoring the GV of a request object,
so we should never need to write mutations that do that.
- We updated the supervisor secret generation to no longer manually set an owner
reference to the deployment since the middleware code now does this. I think we
still need some way to make an initial event for the secret generator
controller, which involves knowing the namespace and the name of the generated
secret, so I still wired the deployment through. We could use a namespace/name
tuple here, but I was lazy.
