- Automatically try to fall back to using StartTLS when using TLS
doesn't work. Only complain when both don't work.
- Remember (in-memory) which one worked and keeping using that one
in the future (unless the pod restarts).
- This enhances our LDAP client code to make it possible to optionally
dial an LDAP server without TLS and then use StartTLS to upgrade
the connection to TLS.
- The controller for LDAPIdentityProviders is not using this option
yet. That will come in a future commit.
Previously, our controllers would automatically create a CredentialIssuer with a singleton name. The helpers we had for this also used "raw" client access and did not take advantage of the informer cache pattern.
With this change, the CredentialIssuer is always created at install time in the ytt YAML. The controllers now only update the existing CredentialIssuer status, and they do so using the informer cache as much as possible.
This change is targeted at only the kubecertagent controller to start. The impersonatorconfig controller will be updated in a following PR along with other changes.

Reflect the upstream group membership into the Supervisor's
downstream tokens, so they can be added to the user's
identity on the workload clusters.
LDAP group search is configurable on the
LDAPIdentityProvider resource.
This change makes it easier to understand misconfigurations caused
by issuers with extraneous trailing slashes.

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.

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.

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).

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`).

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.

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.

Also force the LDAP server pod to restart whenever the LDIF file
changes, so whenever you redeploy the tools deployment with a new test
user password the server will be updated.
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.
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.
