Also changed the access token lifetime to be 2 minutes instead of 15
since we now have cert caching.

supervisor gc: use singleton queue
The supervisor treats all events the same hence it must use a
singleton queue.

Updated the integration test to remove the data race caused by
calling methods on testing.T outside of the main test go routine.

Split out kube-cert-agent service account and bindings.
Followup on the previous comment to split apart the ServiceAccount of the kube-cert-agent and the main concierge pod. This is a bit cleaner and ensures that in testing our main Concierge pod never requires any privileged permissions.

Run kube-cert-agent pod as Concierge ServiceAccount.
Since 0dfb3e95c5, we no longer directly create the kube-cert-agent Pod, so our "use"
permission on PodSecurityPolicies no longer has the intended effect. Since the deployments controller is now the
one creating pods for us, we need to get the permission on the PodSpec of the target pod instead, which we do somewhat
simply by using the same service account as the main Concierge pods.

We still set `automountServiceAccountToken: false`, so this should not actually give any useful permissions to the
agent pod when running.

impersonator: add support for service account token authentication
This change updates the impersonator logic to pass through requests
that authenticated via a bearer token that asserts a UID.  This
allows us to support service account tokens (as well as any other
form of token based authentication).

Add a new "legacy pod cleaner" controller.
This controller is responsible for cleaning up kube-cert-agent pods that were deployed by previous versions.

They are easily identified because they use a different `kube-cert-agent.pinniped.dev` label compared to the new agent pods (`true` vs. `v2`).

Refactor kube-cert-agent controllers to use a Deployment.
This is a relatively large rewrite of much of the kube-cert-agent controllers. Instead of managing raw Pod objects, they now create a single Deployment and let the builtin k8s controller handle it from there.

This reduces the amount of code we need and should handle a number of edge cases better, especially those where a Pod becomes "wedged" and needs to be recreated.

Remove unneeded OIDC-related sleeps in tests.
Now that we have the fix from https://github.com/kubernetes/kubernetes/pull/97693, we no longer need these sleeps.
The underlying authenticator initialization is still asynchronous, but should happen within a few milliseconds.

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.

Ryan Richard 83085aa3d6 Retest the server connection when the bind Secret has changed
Unfortunately, Secrets do not seem to have a Generation field, so we
use the ResourceVersion field instead. This means that any change to
the Secret will cause us to retry the connection to the LDAP server,
even if the username and password fields in the Secret were not
changed. Seems like an okay trade-off for this early draft of the
controller compared to a more complex implementation.

Ryan Richard 8e438e22e9 Only test the server connection when the spec has changed
This early version of the controller is not intended to act as an
ongoing health check for your upstream LDAP server. It will connect
to the LDAP server to essentially "lint" your configuration once.
It will do it again only when you change your configuration. To account
for transient errors, it will keep trying to connect to the server
until it succeeds once.

This commit does not include looking for changes in the associated bind
user username/password Secret.

Ryan Richard 51263a0f07 Return unauthenticated instead of error for bad username or password
- Bad usernames and passwords aren't really errors, since they are
  based on end-user input.
- Other kinds of authentication failures are caused by bad configuration
  so still treat those as errors.
- Empty usernames and passwords are already prevented by our endpoint
  handler, but just to be safe make sure they cause errors inside the
  authenticator too.
