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.

This reverts commit 4a28d1f800.
This commit was originally made to fix a bug that caused TokenCredentialRequest
to become slow when the server was idle for an extended period of time. This was
to address a Kubernetes issue that was fixed in 1.19.5 and onward. We are now
running with Kubernetes 1.20, so we should be able to pick up this fix.
This change updates our clients to always set an owner ref when:
1. The operation is a create
2. The object does not already have an owner ref set

- Only sync on add/update of secrets in the same namespace which
have the "storage.pinniped.dev/garbage-collect-after" annotation, and
also during a full resync of the informer whenever secrets in the
same namespace with that annotation exist.
- Ignore deleted secrets to avoid having this controller trigger itself
unnecessarily when it deletes a secret. This controller is never
interested in deleted secrets, since its only job is to delete
existing secrets.
- No change to the self-imposed rate limit logic. That still applies
because secrets with this annotation will be created and updated
regularly while the system is running (not just during rare system
configuration steps).
We stared at this very carefully and we don't think there are any structural changes. Maybe something small happened to get the RNG off by one?

This is a bit more clear. We're changing this now because it is a non-backwards-compatible change that we can make now since none of this RFC8693 token exchange stuff has been released yet.

Fosite overrides the `Cache-Control` header we set, which is basically fine even though it's not exactly what we want.

From RFC2616 (https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2):
> It MUST be possible to combine the multiple header fields into one "field-name: field-value" pair,

This was correct before, but this simplifes a bit and shaves off a few bytes from the response.
Signed-off-by: Matt Moyer <moyerm@vmware.com>
The bug itself has to do with when headers are streamed to the client. Once a wrapped handler has sent any bytes to the `http.ResponseWriter`, the value of the map returned from `w.Header()` no longer matters for the response. The fix is fairly trivial, which is to add those response headers before invoking the wrapped handler.
The existing unit test didn't catch this due to limitations in `httptest.NewRecorder()`. It is now replaced with a new test that runs a full HTTP test server, which catches the previous bug.

- Refactor the test to avoid testing a private method and instead
always test the results of running the controller.
- Also remove the `if testing.Short()` check because it will always
be short when running unit tests. This prevented the unit test
from ever running, both locally and in CI.

We believe this API is more forwards compatible with future secrets management
use cases. The implementation is a cry for help, but I was trying to follow the
previously established pattern of encapsulating the secret generation
functionality to a single group of packages.
This commit makes a breaking change to the current OIDCProvider API, but that
OIDCProvider API was added after the latest release, so it is technically still
in development until we release, and therefore we can continue to thrash on it.
I also took this opportunity to make some things private that didn't need to be
public.

- Also add more log statements to the controller

When we try to decode with the wrong decryption key, we could get any number of
error messages, depending on what failure mode we are in (couldn't authenticate
plaintext after decryption, couldn't deserialize, etc.). This change makes the
test weaker, but at least we know we will get an error message in the case where
the decryption key is wrong.

This also sets the CSRF cookie Secret's OwnerReference to the Pod's grandparent
Deployment so that when the Deployment is cleaned up, then the Secret is as
well.

This CSRF cookie needs to be included on the request to the callback endpoint triggered by the redirect from the OIDC upstream provider. This is not allowed by `Same-Site=Strict` but is allowed by `Same-Site=Lax` because it is a "cross-site top-level navigation" [1].
We didn't catch this earlier with our Dex-based tests because the upstream and downstream issuers were on the same parent domain `*.svc.cluster.local` so the cookie was allowed even with `Strict` mode.
