Ryan Richard 76bd462cf8 Implement very rough skeleton of the start of a supervisor server
- This is just stab at a starting place because it felt easier to
  put something down on paper than to keep staring at a blank page

kubecertagent: use initial event for when key can't be found
This should fix integration tests running on clusters that don't have
visible controller manager pods (e.g., GKE). Pinniped should boot, not
find any controller manager pods, but still post a status in the CIC.

I also updated a test helper so that we could tell the difference
between when an event was not added and when an event was added with
an empty key.

Plumb through ImagePullSecrets to agent pod
Right now in the YTT templates we assume that the agent pods are gonna use
the same image as the main Pinniped deployment, so we can use the same logic
for the image pull secrets.

Andrew Keesler 69137fb6b9 kube_config_info_publisher.go no longer watches cic's with an informer
Simplifies the implementation, makes it more consistent with other
updaters of the cic (CredentialIssuerConfig), and also retries on
update conflicts

Ryan Richard 381811b36f Refactor constructor params of the kubecertagent pkg's controllers
- Only inject things through the constructor that the controller
  will need
- Use pkg private constants when possible for things that are not
  actually configurable by the user
- Make the agent pod template private to the pkg
- Introduce a test helper to reduce some duplicated test code
- Remove some `it.Focus` lines that were accidentally committed, and
  repair the broken tests that they were hiding

Fix kubecertagent deleter test to reconcile on pod template fields
I think we want to reconcile on these pod template fields so that if
someone were to redeploy Pinniped with a new image for the agent, the
agent would get updated immediately. Before this change, the agent image
wouldn't get updated until the agent pod was deleted.

internal/provider -> internal/dynamiccert
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.

Ryan Richard 80a520390b Rename many of resources that are created in Kubernetes by Pinniped
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

Fix base64 encoding style in webhookcachefiller.
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.

Ryan Richard 20b21e8639 Prefactor: Move updating of APIService to a separate controller
- 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

Use EC crypto (instead of RSA) to workaround weird test timeout
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...).

  new behavior

  calling the new library.SkipUnlessClusterHasCapability test helper

- Add copyrights where they were missing
