New resource naming conventions:
- Do not repeat the Kind in the name,
e.g. do not call it foo-cluster-role-binding, just call it foo
- Names will generally start with a prefix to identify our component,
so when a user lists all objects of that kind, they can tell to which
component it is related,
e.g. `kubectl get configmaps` would list one named "pinniped-config"
- It should be possible for an operator to make the word "pinniped"
mostly disappear if they choose, by specifying the app_name in
values.yaml, to the extent that is practical (but not from APIService
names because those are hardcoded in golang)
- Each role/clusterrole and its corresponding binding have the same name
- Pinniped resource names that must be known by the server golang code
are passed to the code at run time via ConfigMap, rather than
hardcoded in the golang code. This also allows them to be prepended
with the app_name from values.yaml while creating the ConfigMap.
- Since the CLI `get-kubeconfig` command cannot guess the name of the
CredentialIssuerConfig resource in advance anymore, it lists all
CredentialIssuerConfig in the app's namespace and returns an error
if there is not exactly one found, and then uses that one regardless
of its name
Eventually we could refactor to remove support for the old APIs, but they are so similar that a single implementation seems to handle both easily.

This was previously using the unpadded (raw) base64 encoder, which worked sometimes (if the CA happened to be a length that didn't require padding). The correct encoding is the `base64.StdEncoding` one that includes padding.

- Add flag parsing and help messages for root command,
`exchange-credential` subcommand, and new `get-kubeconfig` subcommand
- The new `get-kubeconfig` subcommand is a work in progress in this
commit
- Also add here.Doc() and here.Docf() to enable nice heredocs in
our code
- 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
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...).

- 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.
So that operators won't look at the lifetime of the CA cert and be
like, "wtf, why does the serving cert have the lifetime that I
specified, but its CA cert is valid for 100 years".

This should simplify our build/test setup quite a bit, since it means we have only a single module (at the top level) with all hand-written code. I'll leave `module.sh` alone for now but we may be able to simplify that a bit more.

- Controller and aggregated API server are allowed to run
- Keep retrying to borrow the cluster signing key in case the failure
to get it was caused by a transient failure
- The CredentialRequest endpoint will always return an authentication
failure as long as the cluster signing key cannot be borrowed
- Update which integration tests are skipped to reflect what should
and should not work based on the cluster's capability under this
new behavior
- Move CreateOrUpdateCredentialIssuerConfig() and related methods
to their own file
- Update the CredentialIssuerConfig's Status every time we try to
refresh the cluster signing key
- Indicate the success or failure of the cluster signing key strategy
- Also introduce the concept of "capabilities" of an integration test
cluster to allow the integration tests to be run against clusters
that do or don't allow the borrowing of the cluster signing key
- Tests that are not expected to pass on clusters that lack the
borrowing of the signing key capability are now ignored by
calling the new library.SkipUnlessClusterHasCapability test helper
- Rename library.Getenv to library.GetEnv
- Add copyrights where they were missing
We are seeing between 1 and 2 minutes of difference between the current time
reported in the API server pod and the pinniped pods on one of our testing
environments. Hopefully this change makes our tests pass again.

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.
