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.

These are tricky because a real load balancer controller (e.g., on GKE) will overwrite and set NodePort, so we can't blindly set the desired state of this fields.
For now, we will just skip reconciling these. In the future, we could be more clever about merging them together with the current state.

If the only thing that has changed about a strategy is the LastUpdated timestamp, then we should not update the object.

This updates the code to use a different mechanism for driving desired state:
- Read existing object
- If it does not exist, create desired object
- If it does exist, make a copy and set all the desired fields
- Do a deepequal to see if an update is necessary.

We also no longer need an initial event, since we don't do anything unless the CredentialIssuer exists, so we'll always be triggered at the appropriate time.

- 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).
