impersonator: run as a distinct SA with minimal permissions
This change updates the impersonation proxy code to run as a
distinct service account that only has permission to impersonate
identities.  Thus any future vulnerability that causes the
impersonation headers to be dropped will fail closed instead of
escalating to the concierge's default service account which has
significantly more permissions.

impersonator: honor anonymous authentication being disabled
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).

Fix a data race in TestImpersonationProxy.
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.

Refactor TestImpersonationProxy "apply annotation" test for clarity.
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.

Allow some flexibility in "kubectl logs --tail=10" test.
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.

In TestImpersonationProxy tests, avoid mutating anything in parallel block of tests.
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.

Fix TestImpersonationProxy on EKS.
The admin kubeconfigs we have on EKS clusters are a bit different from others, because there is no certificate/key (EKS does not use certificate auth).

This code didn't quite work correctly in that case. The fix is to allow the case where `tlsConfig.GetClientCertificate` is non-nil, but returns a value with no certificates.

impersonation proxy: add nested impersonation support
This change updates the impersonator logic to use the delegated
authorizer for all non-rest verbs such as impersonate.  This allows
it to correctly perform authorization checks for incoming requests
that set impersonation headers while not performing unnecessary
checks that are already handled by KAS.

The audit layer is enabled to track the original user who made the
request.  This information is then included in a reserved extra
field original-user-info.impersonation-proxy.concierge.pinniped.dev
as a JSON blob.

- This new value is not used on main at this time. We intend to use

Deflake TestImpersonationProxy (especially on EKS).
This test could flake if the load balancer hostname was provisioned but is not yet resolving in DNS from the test process.

The fix is to retry this step for up to 5 minutes.
