These controllers were a bit inconsistent. There were cases where the controllers ran out of the expected order and the custom labels might not have been applied.
We should still plan to remove this label handling or move responsibility into the middleware layer, but this avoids any regression.

This field is a new tagged-union style field that describes how clients can connect using each successful strategy.

We don't support using the impersonate headers through the impersonation
proxy yet, so this integration test is a negative test which asserts
that we get an error.
- The CA cert will end up in the end user's kubeconfig on their client
machine, so if it changes they would need to fetch the new one and
update their kubeconfig. Therefore, we should avoid changing it as
much as possible.
- Now the controller writes the CA to a different Secret. It writes both
the cert and the key so it can reuse them to create more TLS
certificates in the future.
- For now, it only needs to make more TLS certificates if the old
TLS cert Secret gets deleted or updated to be invalid. This allows
for manual rotation of the TLS certs by simply deleting the Secret.
In the future, we may want to implement some kind of auto rotation.
- For now, rotation of both the CA and TLS certs will also happen if
you manually delete the CA Secret. However, this would cause the end
users to immediately need to get the new CA into their kubeconfig,
so this is not as elegant as a normal rotation flow where you would
have a window of time where you have more than one CA.
Also fixes our sitemap to have correct `lastmod` times when built locally (it was already correct on Netlify).

Should work on cluster which have:
- load balancers not supported, has squid proxy (e.g. kind)
- load balancers supported, has squid proxy (e.g. EKS)
- load balancers supported, no squid proxy (e.g. GKE)
When testing with a load balancer, call the impersonation proxy through
the load balancer.
Also, added a new library.RequireNeverWithoutError() helper.

This flag selects a CredentialIssuer to use when detecting what mode the Concierge is in on a cluster. If not specified, the command will look for a single CredentialIssuer. If there are multiple, then the flag is required.

Also update concierge_impersonation_proxy_test.go integration test
to use real TLS when calling the impersonator.

These are prone to breaking when stdr is upgraded because they rely on the exact ordering of keys in the log message. If we have more problems we can rewrite the assertions to be more robust, but for this time I'm just fixing them to match the new output.

The login commands now expect either `--concierge-mode ImpersonationProxy` or `--concierge-mode TokenCredentialRequestAPI` (the default).
This is partly a style choice, but I also think it helps in case we need to add a third major mode of operation at some point.
I also cleaned up some other minor style items in the help text.

There is a new feature in 1.20 that creates a ConfigMap by default in each namespace: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.20.md#introducing-rootcaconfigmap
This broke this test because it assumed that all the ConfigMaps in the ephemeral test namespace were those created by the test code. The fix is to add a test label and rewrite our assertions to filter with it.

Adds a new optional `spec.impersonationProxyInfo` field to hold the URL and CA data for the impersonation proxy, as well as some additional status condition constants for describing the current status of the impersonation proxy.
