The thing we're waiting for is mostly that DNS is resolving, the ELB is listening, and connections are making it to the proxy.

All controller unit tests were accidentally using a timeout context
for the informers, instead of a cancel context which stays alive until
each test is completely finished. There is no reason to risk
unpredictable behavior of a timeout being reached during an individual
test, even though with the previous 3 second timeout it could only be
reached on a machine which is running orders of magnitude slower than
usual, since each test usually runs in about 100-300 ms. Unfortunately,
sometimes our CI workers might get that slow.
This sparked a review of other usages of timeout contexts in other
tests, and all of them were increased to a minimum value of 1 minute,
under the rule of thumb that our tests will be more reliable on slow
machines if they "pass fast and fail slow".
This time, don't use the Squid proxy if the cluster supports real external load balancers (as in EKS/GKE/AKS).

If the test is run immediately after the Concierge is installed, the API server can still have broken discovery data and return an error on the first call.
This commit adds a retry loop to attempt this first kubectl command for up to 60s before declaring failure.

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.
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 is a partial revert of 288d9c999e. For some reason it didn't occur to me
that we could do it this way earlier. Whoops.
This also contains a middleware update: mutation funcs can return an error now
and short-circuit the rest of the request/response flow. The idea here is that
if someone is configuring their kubeclient to use middleware, they are agreeing
to a narrow-er client contract by doing so (e.g., their TokenCredentialRequest's
must have an Spec.Authenticator.APIGroup set).
I also updated some internal/groupsuffix tests to be more realistic.

I think the reason we were seeing flakes here is because the kube cert agent

Yes, this is a huge commit.
The middleware allows you to customize the API groups of all of the
*.pinniped.dev API groups.
Some notes about other small things in this commit:
- We removed the internal/client package in favor of pkg/conciergeclient. The
two packages do basically the same thing. I don't think we use the former
anymore.
- We re-enabled cluster-scoped owner assertions in the integration tests.
This code was added in internal/ownerref. See a0546942 for when this
assertion was removed.
- Note: the middlware code is in charge of restoring the GV of a request object,
so we should never need to write mutations that do that.
- We updated the supervisor secret generation to no longer manually set an owner
reference to the deployment since the middleware code now does this. I think we
still need some way to make an initial event for the secret generator
controller, which involves knowing the namespace and the name of the generated
secret, so I still wired the deployment through. We could use a namespace/name
tuple here, but I was lazy.

The group claims read from the session cache file are loaded as `[]interface{}` (slice of empty interfaces) so when we previously did a `groups, _ := idTokenClaims[oidc.DownstreamGroupsClaim].([]string)`, then `groups` would always end up nil.
The solution I tried here was to convert the expected value to also be `[]interface{}` so that `require.Equal(t, ...)` does the right thing.
This bug only showed up in our acceptance environnment against Okta, since we don't have any other integration test coverage with IDPs that pass a groups claim.

We were seeing a race in this test code since the require.NoError() and

See comment. This is at least a first step to make our GKE acceptance

- Only sync on add/update of secrets in the same namespace which
have the "storage.pinniped.dev/garbage-collect-after" annotation, and
also during a full resync of the informer whenever secrets in the
same namespace with that annotation exist.
- Ignore deleted secrets to avoid having this controller trigger itself
unnecessarily when it deletes a secret. This controller is never
interested in deleted secrets, since its only job is to delete
existing secrets.
- No change to the self-imposed rate limit logic. That still applies
because secrets with this annotation will be created and updated
regularly while the system is running (not just during rare system
configuration steps).
This is a bit more clear. We're changing this now because it is a non-backwards-compatible change that we can make now since none of this RFC8693 token exchange stuff has been released yet.

We believe this API is more forwards compatible with future secrets management

This commit makes a breaking change to the current OIDCProvider API, but that
OIDCProvider API was added after the latest release, so it is technically still
in development until we release, and therefore we can continue to thrash on it.
I also took this opportunity to make some things private that didn't need to be

- Setting a Secret in the supervisor's namespace with a special name
will cause it to get picked up and served as the supervisor's TLS
cert for any request which does not have a matching SNI cert.
- This is especially useful for when there is no DNS record for an
issuer and the user will be accessing it via IP address. This
is not how we would expect it to be used in production, but it
might be useful for other cases.
- Includes a new integration test
- Also suppress all of the warnings about ignoring the error returned by
Close() in lines like `defer x.Close()` to make GoLand happier
Based on our experiences today with GKE, it will be easier for our users
to configure Ingress health checks if the healthz endpoint is available
on the same public port as the OIDC endpoints.
Also add an integration test for the healthz endpoint now that it is
public.
Also add the optional `containers[].ports.containerPort` to the
supervisor Deployment because the GKE docs say that GKE will look
at that field while inferring how to invoke the health endpoint. See
https://cloud.google.com/kubernetes-engine/docs/concepts/ingress#def_inf_hc
- Not used by any of our integration test clusters yet
- Planning to use it later for the kind clusters and maybe for
the acceptance clusters too (although the acceptance clusters might
not need to use self-signed certs so maybe not)
- It didn't matter before because it would be cleaned up by a
t.Cleanup() function, but now that we might loop twice it will matter
during the second time through the loop
EC keys are smaller and take less time to generate. Our integration
tests were super flakey because generating an RSA key would take up to
10 seconds *gasp*. The main token verifier that we care about is
Kubernetes, which supports P256, so hopefully it won't be that much of
an issue that our default signing key type is EC. The OIDC spec seems
kinda squirmy when it comes to using non-RSA signing algorithms...
