c6c2c525a6 Upgrade the linter and fix all new linter warnings
Also fix some tests that were broken by bumping golang and dependencies
in the previous commits.

Note that in addition to changes made to satisfy the linter which do not
impact the behavior of the code, this commit also adds ReadHeaderTimeout
to all usages of http.Server to satisfy the linter (and because it
seemed like a good suggestion).

Update all deps to latest where possible, bump Kube deps to v0.23.1
Highlights from this dep bump:

1. Made a copy of the v0.4.0 github.com/go-logr/stdr implementation
   for use in tests.  We must bump this dep as Kube code uses a
   newer version now.  We would have to rewrite hundreds of test log
   assertions without this copy.
2. Use github.com/felixge/httpsnoop to undo the changes made by
   ory/fosite#636 for CLI based login flows.  This is required for
   backwards compatibility with older versions of our CLI.  A
   separate change after this will update the CLI to be more
   flexible (it is purposefully not part of this change to confirm
   that we did not break anything).  For all browser login flows, we
   now redirect using http.StatusSeeOther instead of http.StatusFound.
3. Drop plog.RemoveKlogGlobalFlags as klog no longer mutates global
   process flags
4. Only bump github.com/ory/x to v0.0.297 instead of the latest
   v0.0.321 because v0.0.298+ pulls in a newer version of
   go.opentelemetry.io/otel/semconv which breaks k8s.io/apiserver.
   We should update k8s.io/apiserver to use the newer code.
5. Migrate all code from k8s.io/apimachinery/pkg/util/clock to
   k8s.io/utils/clock and k8s.io/utils/clock/testing
6. Delete testutil.NewDeleteOptionsRecorder and migrate to the new
   kubetesting.NewDeleteActionWithOptions
7. Updated ExpectedAuthorizeCodeSessionJSONFromFuzzing caused by
   fosite's new rotated_secrets OAuth client field.  This new field
   is currently not relevant to us as we have no private clients.

ca2cc40769 Add impersonationProxyServerPort to the Concierge's static ConfigMap
- Used to determine on which port the impersonation proxy will bind
- Defaults to 8444, which is the old hard-coded port value
- Allow the port number to be configured to any value within the
  range 1024 to 65535
- This commit does not include adding new config knobs to the ytt
  values file, so while it is possible to change this port without
  needing to recompile, it is not convenient

Do not rotate impersonation proxy signer CA unless necessary
This change fixes a copy paste error that led to the impersonation
proxy signer CA being rotated based on the configuration of the
rotation of the aggregated API serving certificate.  This would lead
to occasional "Unauthorized" flakes in our CI environments that
rotate the serving certificate at a frequent interval.

Updated the certs_expirer controller logs to be more detailed.

Updated CA common names to be more specific (this does not update
any previously generated CAs).

certauthority: tolerate larger clock skew between API server and pinniped
This change updates our certificate code to use the same 5 minute
backdate that is used by the Kubernetes controller manager.  This
helps to account for clock skews between the API servers and the
kubelets that are running the pinniped pods.  While this backdating
reflects a large percentage of the lifetime of our short lived
certificates (100% for the 5 minute client certificates), even a 10
minute irrevocable client certificate is within our limits.  When
we move to the CSR based short lived certificates, they will always
have at least a 15 minute lifetime (5 minute backdating plus 10 minute
minimum valid duration).

impersonatorconfig: only unload dynamiccert when proxy is disabled
In the upstream dynamiccertificates package, we rely on two pieces
of code:

1. DynamicServingCertificateController.newTLSContent which calls
   - clientCA.CurrentCABundleContent
   - servingCert.CurrentCertKeyContent
2. unionCAContent.VerifyOptions which calls
   - unionCAContent.CurrentCABundleContent

This results in calls to our tlsServingCertDynamicCertProvider and
impersonationSigningCertProvider.  If we Unset these providers, we
subtly break these consumers.  At best this results in test slowness
and flakes while we wait for reconcile loops to converge.  At worst,
it results in actual errors during runtime.  For example, we
previously would Unset the impersonationSigningCertProvider on any
sync loop error (even a transient one caused by a network blip or
a conflict between writes from different replicas of the concierge).
This would cause us to transiently fail to issue new certificates
from the token credential require API.  It would also cause us to
transiently fail to authenticate previously issued client certs
(which results in occasional Unauthorized errors in CI).

c82f568b2c certauthority.go: Refactor issuing client versus server certs
We were previously issuing both client certs and server certs with
both extended key usages included. Split the Issue*() methods into
separate methods for issuing server certs versus client certs so
they can have different extended key usages tailored for each use
case.

Also took the opportunity to clean up the parameters of the Issue*()
methods and New() methods to more closely match how we prefer to call
them. We were always only passing the common name part of the
pkix.Name to New(), so now the New() method just takes the common name
as a string. When making a server cert, we don't need to set the
deprecated common name field, so remove that param. When making a client
cert, we're always making it in the format expected by the Kube API
server, so just accept the username and group as parameters directly.

0b300cbe42 Use TokenCredentialRequest instead of base64 token with impersonator
To make an impersonation request, first make a TokenCredentialRequest
to get a certificate. That cert will either be issued by the Kube
API server's CA or by a new CA specific to the impersonator. Either
way, you can then make a request to the impersonator and present
that client cert for auth and the impersonator will accept it and
make the impesonation call on your behalf.

The impersonator http handler now borrows some Kube library code
to handle request processing. This will allow us to more closely
mimic the behavior of a real API server, e.g. the client cert
auth will work exactly like the real API server.

d8c6894cbc All controller unit tests should not cancel context until test is over
All controller unit tests were accidentally using a timeout context
for the informers, instead of a cancel context which stays alive until
each test is completely finished. There is no reason to risk
unpredictable behavior of a timeout being reached during an individual
test, even though with the previous 3 second timeout it could only be
reached on a machine which is running orders of magnitude slower than
usual, since each test usually runs in about 100-300 ms. Unfortunately,
sometimes our CI workers might get that slow.

This sparked a review of other usages of timeout contexts in other
tests, and all of them were increased to a minimum value of 1 minute,
under the rule of thumb that our tests will be more reliable on slow
machines if they "pass fast and fail slow".

b102aa8991 In unit test, wait for obj from informer instead of resource version
In impersonator_config_test.go, instead of waiting for the resource
version to appear in the informers, wait for the actual object to
appear.

This is an attempt to resolve flaky failures that only happen in CI,
but it also cleans up the test a bit by avoiding inventing fake resource
version numbers all over the test.
