This thing is supposed to be used to help our CredentialRequest handler issue certs with a dynamic
CA keypair.

3 main reasons:
- The cert and key that we store in this object are not always used for TLS.
- The package name "provider" was a little too generic.
- dynamiccert.Provider reads more go-ish than provider.DynamicCertProvider.

- Lots of TODOs added that need to be resolved to finish this WIP
- execer_test.go seems like it should be passing, but it fails (sigh)

This also has fallback compatibility support if no IDP is specified and there is exactly one IDP in the cache.

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
- 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
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.

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.

- Add a unit test for each cert controller
- Make DynamicTLSServingCertProvider an interface and use a mutex
internally
- Create a shared ToPEM function instead of having two very similar
functions
- Move the ObservableWithInformerOption test helper to testutils
- Rename some variables and imports
- Refactors the existing cert generation code into controllers
which read and write a Secret containing the certs
- Does not add any new functionality yet, e.g. no new handling
for cert expiration, and no leader election to allow for
multiple servers running simultaneously
- This commit also doesn't add new tests for the cert generation
code, but it should be more unit testable now as controllers
- No functional changes
- Move all the stuff about clients and controllers into the controller
package
- Add more comments and organize the code more into more helper
functions to make each function smaller
- Previously the golang code would create a Service and an APIService.
The APIService would be given an owner reference which pointed to
the namespace in which the app was installed.
- This prevented the app from being uninstalled. The namespace would
refuse to delete, so `kapp delete` or `kubectl delete` would fail.
- The new approach is to statically define the Service and an APIService
in the deployment.yaml, except for the caBundle of the APIService.
Then the golang code will perform an update to add the caBundle at
runtime.
- When the user uses `kapp deploy` or `kubectl apply` either tool will
notice that the caBundle is not declared in the yaml and will
therefore avoid editing that field.
- When the user uses `kapp delete` or `kubectl delete` either tool will
destroy the objects because they are statically declared with names
in the yaml, just like all of the other objects. There are no
ownerReferences used, so nothing should prevent the namespace from
being deleted.
- This approach also allows us to have less golang code to maintain.
- In the future, if our golang controllers want to dynamically add
an Ingress or other objects, they can still do that. An Ingress
would point to our statically defined Service as its backend.

- Seems like the next step is to allow override of the CA bundle; I didn't
do that here for simplicity of the commit, but seems like it is the right
thing to do in the future.
- Also includes bumping the api and client-go dependencies to the newer
version which also moved LoginDiscoveryConfig to the
crds.placeholder.suzerain-io.github.io group in the generated code
