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,
> without changing the semantics of the message, by appending each subsequent field-value to the first,
> each separated by a comma.
This was correct before, but this simplifes a bit and shaves off a few bytes from the response.

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.

- AudienceMatchingStrategy: we want to use the default matcher from
fosite, so remove that line
- AllowedPromptValues: We can use the default if we add a small
change to the auth_handler.go to account for it (in a future commit)
- MinParameterEntropy: Use the fosite default to make it more likely
that off the shelf OIDC clients can work with the supervisor

- Also add more log statements to the controller
- Also have the controller apply a rate limit to itself, to avoid
having a very chatty controller that runs way more often than is
needed.
- Also add an integration test for the controller's behavior.

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.
Obviously this controller implementation has a lot of issues, but it will at
least get us started.

There is still a test failing, but I am sure it is a simple fix hiding in the

- This is to make it easier for the token exchange branch to also edit
this test without causing a lot of merge conflicts with the
refresh token branch, to enable parallel development of closely

- This refactor will allow us to add new test tables for the

an initial successful authcode exchange has already happened

`token_endpoint_auth_signing_alg_values_supported` is only related to

TokenURL is used by Fosite to validate clients authenticating with the

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.
