WithImpersonation already deletes impersonation headers and has done
so since the early days:
https://github.com/kubernetes/kubernetes/pull/36769
ensureNoImpersonationHeaders will still reject any request that has
impersonation headers set so we will always fail closed.

When anonymous authentication is disabled, the impersonation proxy
will no longer authenticate anonymous requests other than calls to
the token credential request API (this API is used to retrieve
credentials and thus must be accessed anonymously).

There was nothing to guarantee that _all_ Supervisor pods would be ready to handle this request. We saw a rare test flake where the LDAPIdentityProvider was marked as ready but one of the Supervisor pods didn't have it loaded yet and returned an HTTP 422 error (`Unprocessable Entity: No upstream providers are configured`).

The `require.Eventually()` function runs the body of the check in a separate goroutine, so it's not safe to use other `require` assertions as we did here. Our `library.RequireEventuallyWithoutError()` function does not spawn a goroutine, so it's safer to use here.

When a CredentialIssuer is switched from one service type to another (or switched to disabled mode), the `impersonatorconfig` controller will delete the previous Service, if any. Normally one Concierge pod will succeed to delete this initially and any other pods will see a NotFound error.
Before this change, the NotFound would bubble up and cause the strategy to enter a ErrorDuringSetup status until the next reconcile loop. We now handle this case without reporting an error.

This typo wasn't caught in testing because 1) the Kubernetes API ignores the unknown field and 2) the `type` field defaults to `LoadBalancer` anyway, so things behave as expected.
Even though this doesn't cause any large problems, it's quite confusing.

The LastUpdateTime is no longer updated on every resync. It only changes if the underlying status has changed, so that it effectively shows when the transition happened.
This change happened in ab750f48aa, but we missed this test. It only fails when it has been more than ten minutes since the CredentialIssuer transitioned into a healthy state, but that can happen in our long-running CI environments.

This test felt overly complex and some of the cleanup logic wasn't 100% correct (it didn't clean up in all cases).
The new code is essentially the same flow but hopefully easier to read.

We see that occasionally kubectl returns 11 lines (probably related to https://github.com/kubernetes/kubernetes/issues/72628).
This test doesn't need to be so picky, so now it allows +/- one line from the expected count.

We had this one test that mutated the CredentialIssuer, which could cause the impersonation proxy to blip on one or both of the running concierge pods. This would sometimes break other concurrently running tests.
Instead, this bit of code is split into a separate non-concurrent test.

The new version has different behavior for the `nonce` claim, which is now omitted if it would be empty (see https://github.com/ory/fosite/pull/570).

This required a weird hack because some of the Fosite tests (or a transitive dependency of them) depends on a newer version of gRPC that's incompatible with the Kubernetes runtime version we use. It wasn't as simple as just replacing the gRPC module with an older version, because in the latest versions of gRPC, they split out the "examples" packages into their own module. This new module name doesn't exist at the old version.
Ultimately, the workaround was to make a fake "examples" module locally. This module can be empty because we never actually depend on that code (it's only used in transitive dependency tests).
