Add a new "legacy pod cleaner" controller.
This controller is responsible for cleaning up kube-cert-agent pods that were deployed by previous versions.

They are easily identified because they use a different `kube-cert-agent.pinniped.dev` label compared to the new agent pods (`true` vs. `v2`).

Refactor kube-cert-agent controllers to use a Deployment.
This is a relatively large rewrite of much of the kube-cert-agent controllers. Instead of managing raw Pod objects, they now create a single Deployment and let the builtin k8s controller handle it from there.

This reduces the amount of code we need and should handle a number of edge cases better, especially those where a Pod becomes "wedged" and needs to be recreated.

6a350aa4e1 Fix some LDAP CA bundle handling
- Make PINNIPED_TEST_LDAP_LDAPS_CA_BUNDLE optional for integration tests
- When there is no CA bundle provided, be careful to use nil instead of
  an empty bundle, because nil means to use the OS defaults

Remove unneeded OIDC-related sleeps in tests.
Now that we have the fix from https://github.com/kubernetes/kubernetes/pull/97693, we no longer need these sleeps.
The underlying authenticator initialization is still asynchronous, but should happen within a few milliseconds.

impersonation proxy: add nested impersonation support
This change updates the impersonator logic to use the delegated
authorizer for all non-rest verbs such as impersonate.  This allows
it to correctly perform authorization checks for incoming requests
that set impersonation headers while not performing unnecessary
checks that are already handled by KAS.

The audit layer is enabled to track the original user who made the
request.  This information is then included in a reserved extra
field original-user-info.impersonation-proxy.concierge.pinniped.dev
as a JSON blob.

83085aa3d6 Retest the server connection when the bind Secret has changed
Unfortunately, Secrets do not seem to have a Generation field, so we
use the ResourceVersion field instead. This means that any change to
the Secret will cause us to retry the connection to the LDAP server,
even if the username and password fields in the Secret were not
changed. Seems like an okay trade-off for this early draft of the
controller compared to a more complex implementation.

8e438e22e9 Only test the server connection when the spec has changed
This early version of the controller is not intended to act as an
ongoing health check for your upstream LDAP server. It will connect
to the LDAP server to essentially "lint" your configuration once.
It will do it again only when you change your configuration. To account
for transient errors, it will keep trying to connect to the server
until it succeeds once.

This commit does not include looking for changes in the associated bind
user username/password Secret.

51263a0f07 Return unauthenticated instead of error for bad username or password
- Bad usernames and passwords aren't really errors, since they are
  based on end-user input.
- Other kinds of authentication failures are caused by bad configuration
  so still treat those as errors.
- Empty usernames and passwords are already prevented by our endpoint
  handler, but just to be safe make sure they cause errors inside the
  authenticator too.

fec3d92f26 Add integration test for upstreamldap.Provider
- The unit tests for upstreamldap.Provider need to mock the LDAP server,
  so add an integration test which allows us to get fast feedback for
  this code against a real LDAP server.
- Automatically wrap the user search filter in parenthesis if it is not
  already wrapped in parens.
- More special handling for using "dn" as the username or UID attribute
  name.
- Also added some more comments to types_ldapidentityprovider.go.tmpl

- The ldap_upstream_watcher.go controller validates the bind secret and

  extent which is convenient without generics in golang.

f6ded84f07 Implement upstream LDAP support in auth_handler.go
- When the upstream IDP is an LDAP IDP and the user's LDAP username and
  password are received as new custom headers, then authenticate the
  user and, if authentication was successful, return a redirect with
  an authcode. Handle errors according to the OAuth/OIDC specs.
- Still does not support having multiple upstream IDPs defined at the
  same time, which was an existing limitation of this endpoint.
- Does not yet include the actual LDAP authentication, which is
  hidden behind an interface from the point of view of auth_handler.go
- Move the oidctestutil package to the testutil directory.
- Add an interface for Fosite storage to avoid a cyclical test
  dependency.
- Add GetURL() to the UpstreamLDAPIdentityProviderI interface.
- Extract test helpers to be shared between callback_handler_test.go
  and auth_handler_test.go because the authcode and fosite storage
  assertions should be identical.
- Backfill Content-Type assertions in callback_handler_test.go.
