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.

The LastUpdateTime is no longer updated on every resync.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 is to allow the use of binary LDAP entry attributes as the UID.
For example, a user might like to configure AD’s objectGUID or maybe
objectSid attributes as the UID attribute.
This negatively impacts the readability of the UID when it did not come
from a binary value, but we're considering this an okay trade-off to
keep things simple for now. In the future, we may offer more
customizable encoding options for binary attributes.
These UIDs are currently only used in the downstream OIDC `sub` claim.
They do not effect the user's identity on the Kubernetes cluster,
which is only based on their mapped username and group memberships from
the upstream identity provider. We are not currently supporting any
special encoding for those username and group name LDAP attributes, so
their values in the LDAP entry must be ASCII or UTF-8 in order for them
to be interpreted correctly.
This test setup should tolerate when the TokenCredentialRequest API isn't quite ready to authenticate the user or issue a cert.

This check is no longer valid, because there can be ephemeral, recoverable errors that show as ErrorDuringSetup.

- 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.

- For testing purposes, we would like to ensure that when we connect
to the LDAP server we cannot accidentally avoid using TLS or StartTLS.
- Also enabled the openldap `memberOf` overlay in case we want to
support group search using `memberOf` in the future.
- This required changes to the docker.io/bitnami/openldap container
image, so we're using our own fork for now. Will submit a PR to
bitnami/openldap to see if they will accept it (or something similar)
upstream.
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.
