`token_endpoint_auth_signing_alg_values_supported` is only related to
private_key_jwt and client_secret_jwt client authentication methods
at the token endpoint, which we do not support. See

This refactors the `UpstreamOIDCIdentityProviderI` interface and its implementations to pass ID token claims through a `*oidctypes.Token` return parameter rather than as a third return parameter.

TokenURL is used by Fosite to validate clients authenticating with the
private_key_jwt method. We don't have any use for this right now, so just leave
this blank until we need it.

dynamicOpenIDConnectECDSAStrategy.GenerateToken().
This commit also ensures that linting and unit tests are passing again.

I'm worried that these errors are going to be really burried from the user, so
add some log statements to try to make them a tiny bit more observable.
Also follow some of our error message convetions by using lowercase error
messages.

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.

We are currently using EC keys to sign ID tokens, so we should reflect that in

We missed this in the original interface specification, but the `grant_type=authorization_code` requires it, per RFC6749 (https://tools.ietf.org/html/rfc6749#section-4.1.3).

This allows the token exchange request to be performed with the correct TLS configuration.
We go to a bit of extra work to make sure the `http.Client` object is cached between reconcile operations so that connection pooling works as expected.

Generate a new cookie for the user and move on as if they had not sent
a bad cookie. Hopefully this will make the user experience better if,
for example, the server rotated cookie signing keys and then a user
submitted a very old cookie.

Also use ConstantTimeCompare() to compare CSRF tokens to prevent
leaking any information in how quickly we reject bad tokens.

This is much nicer UX for an administrator installing a UpstreamOIDCProvider
CRD. They don't have to guess as hard at what the callback endpoint path should
be for their UpstreamOIDCProvider.

Also aggresively refactor for readability:
- Make helper validations functions for each type of storage
- Try to label symbols based on their downstream/upstream use and group them
accordingly

- Also handle several more error cases
- Move RequireTimeInDelta to shared testutils package so other tests
can also use it
- Move all of the oidc test helpers into a new oidc/oidctestutils
package to break a circular import dependency. The shared testutil
package can't depend on any of our other packages or else we
end up with circular dependencies.
- Lots more assertions about what was stored at the end of the
request to build confidence that we are going to pass all of the
right settings over to the token endpoint through the storage, and
also to avoid accidental regressions in that area in the future

Also refactor to get rid of duplicate test structs.
Also also don't default groups ID token claim because there is no standard one.
Also also also add some logging that will hopefully help us in debugging in the
future.

Because we want it to implement an AuthcodeExchanger interface and
do it in a way that will be more unit test-friendly than the underlying
library that we intend to use inside its implementation.
This will allow it to be imported by Go code outside of our repository, which was something we have planned for since this code was written.

- To better support having multiple downstream providers configured,
the authorize endpoint will share a CSRF cookie between all
downstream providers' authorize endpoints. The first time a
user's browser hits the authorize endpoint of any downstream
provider, that endpoint will set the cookie. Then if the user
starts an authorize flow with that same downstream provider or with
any other downstream provider which shares the same domain name
(i.e. differentiated by issuer path), then the same cookie will be
submitted and respected.
- Just in case we are sharing the domain name with some other app,
we sign the value of any new CSRF cookie and check the signature
when we receive the cookie. This wasn't strictly necessary since
we probably won't share a domain name with other apps, but it
wasn't hard to add this cookie signing.
