These configuration knobs are much more human-understandable than the
previous percentage-based threshold flag.
We now allow users to set the lifetime of the serving cert via a ConfigMap.
Previously this was hardcoded to 1 year.

We need a way to validate that this generated code is up to date. I added
a long-term engineering TODO for this.

The rotation is forced by a new controller that deletes the serving cert
secret, as other controllers will see this deletion and ensure that a new
serving cert is created.
Note that the integration tests now have an addition worst case runtime of
60 seconds. This is because of the way that the aggregated API server code
reloads certificates. We will fix this in a future story. Then, the
integration tests should hopefully get much faster.

This switches us back to an approach where we use the Pod "exec" API to grab the keys we need, rather than forcing our code to run on the control plane node. It will help us fail gracefully (or dynamically switch to alternate implementations) when the cluster is not self-hosted.

We don't want people to run codegen.sh directly, because it is meant
to be driven by hack/module.sh. To discourage this behavior, we will hide
codegen.sh away in hack/lib. I don't think this is actually what the
hack/lib directory is for, though...meh.

Runs code generation on a per-module basis. If `CONTAINED` is not set
the code generation is run in a container.
Mount point in docker is randomzied to simulate Concourse.
Introduce K8S_PKG_VERSION to make room to build different versions
eventually.
- Call the auto-generated /healthz endpoint of our aggregated API server
- Use http for liveness even though tcp seems like it might be
more appropriate, because tcp probes cause TLS handshake errors
to appear in our logs every few seconds
- Use conservative timeouts and retries on the liveness probe to avoid
having our container get restarted when it is temporarily slow due
to running in an environment under resource pressure
- Use less conservative timeouts and retries for the readiness probe
to remove an unhealthy pod from the service less conservatively than
restarting the container
- Tuning the settings for retries and timeouts seem to be a mysterious
art, so these are just a first draft
- It would sometimes fail with this error:
namespaces is forbidden: User "tanzu-user-authentication@groups.vmware.com"
cannot list resource "namespaces" in API group "" at the cluster scope
- Seems like it was because the RBAC rule added by the test needs a
moment before it starts to take effect, so change the test to retry
the API until it succeeds or fail after 3 seconds of trying.
- We want to follow the <noun>Request convention.
- The actual operation does not login a user, but it does retrieve a
credential with which they can login.
- This commit includes changes to all LoginRequest-related symbols and
constants to try to update their names to follow the new
CredentialRequest type.

As discussed in API review, this field exists for convenience right
now. Since the username/groups are encoded in the Credential sent in
the LoginRequestStatus, the client still has access to their
user/groups information. We want to remove this for now to be
conservative and limit our API surface area (smaller surface area =
less to maintain). We can always add this back in the future.

- When we call the LoginRequest endpoint in loginrequest_test.go,
do it with an unauthenticated client, to make sure that endpoint works
with unauthenticated clients.
- For tests which want to test using certs returned by LoginRequest to
make API calls back to kube to check if those certs are working, make
sure they start with a bare client and then add only those certs.
Avoid accidentally picking up other kubeconfig configuration like
tokens, etc.

find(1) seems to look at directory entries in the order in which they exist
in the directory fs entry. Let's sort these so that we get the same results
regardless of the order of the directory entries.

- For high availability reasons, we would like our app to scale linearly
with the size of the control plane. Using a DaemonSet allows us to run
one pod on each node-role.kubernetes.io/master node.
- The hope is that the Service that we create should load balance
between these pods appropriately.
