I also started updating the script to deploy the test-webhook instead of
doing TMC stuff. I think the script should live in this repo so that
Pinniped contributors only need to worry about one repo for running
integration tests.
There are a bunch of TODOs in the script, but I figured this was a good
checkpoint. The script successfully runs on my machine and sets up the
test-webhook and pinniped on a local kind cluster. The integration tests
are failing because of some issue with pinniped talking to the test-webhook,
but this is step in the right direction.

This script was basically an alias for `./hack/module.sh unittest`. We even
tell people to run the unit tests via module.sh in our contributing doc.
Let's ditch it - the best line of (shell code) is the one you don't write.
An analagous change was made in CI to use module.sh in place of test-unit.sh.

- For now, build the test-webhook binary in the same container image as
the pinniped-server binary, to make it easier to distribute
- Also fix lots of bugs from the first draft of the test-webhook's
`/authenticate` implementation from the previous commit
- Add a detailed README for the new deploy-test-webhook directory
The webhook still needs to be updated to auto generate its
certificates.
We decided not to give this webhook its own go module for now since
this webhook only pulled in one more dependency, and it is a
dependency that we will most likely need in the future.

- The certs manager controller, along with its sibling certs expirer
and certs observer controllers, are generally useful for any process
that wants to create its own CA and TLS certs, but only if the
updating of the APIService is not included in those controllers
- So that functionality for updating APIServices is moved to a new
controller which watches the same Secret which is used by those
other controllers
- Also parameterize `NewCertsManagerController` with the service name
and the CA common name to make the controller more reusable
- We are not setting an upper limit because Kubernetes might randomly
decide to unschedule our pod in ways that we can't anticipate in
advance, causing very hard to reproduce production bugs.
- We noticed that our app currently uses ~30 MB of memory when idle,
and ~35 MB of memory under some load. So a memory request of 128
MB should be reasonable.

When we use RSA private keys to sign our test certificates, we run
into strange test timeouts. The internal/controller/apicerts package
was timing out on my machine more than once every 3 runs. When I
changed the RSA crypto to EC crypto, this timeout goes away. I'm not
gonna try to figure out what the deal is here because I think it would
take longer than it would be worth (although I am sure it is some fun
story involving prime numbers; the goroutine traces for timed out
tests would always include some big.Int operations involving prime
numbers...).

It looks like requests to our aggregated API service on GKE vacillate
between success and failure until they reach a converged successful
state. I think this has to do with our pods updating the API serving
cert at different times. If only one pod updates its serving cert to
the correct value, then it should respond with success. However, the
other pod would respond with failure. Depending on the load balancing
algorithm that GKE uses to send traffic to pods in a service, we could
end up with a success that we interpret as "all pods have rotated
their certs" when it really just means "at least one pod has rotated
its certs."

- Controllers will automatically run again when there's an error,
but when we want to update CredentialIssuerConfig from server.go
we should be careful to retry on conflicts
- Add unit tests for `issuerconfig.CreateOrUpdateCredentialIssuerConfig()`
which was covered by integration tests in previous commits, but not
covered by units tests yet.
