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).

51c527a965 Change to camel-case for insecureAcceptExternalUnencryptedHttpRequests
- Use camel-case in the static configmap
- Parse the value into a boolean in the go struct instead of a string
- Add test for when unsupported value is used in the configmap
- Run the config_test.go tests in parallel
- Update some paragraphs in configure-supervisor.md for clarity

488f08dd6e Provide a way to override the new HTTP loopback-only validation
Add new deprecated_insecure_accept_external_unencrypted_http_requests
value in values.yaml. Allow it to be a boolean or a string to make it
easier to use (both --data-value and --data-value-yaml will work).

Also:
- Consider "ip6-localhost" and "ip6-loopback" to be loopback addresses
  for the validation
- Remove unused env.SupervisorHTTPAddress var
- Deprecate the `service_http_*` values in values.yaml by renaming them
  and causing a ytt render error when the old names are used

Allow configuration of supervisor endpoints
This change allows configuration of the http and https listeners
used by the supervisor.

TCP (IPv4 and IPv6 with any interface and port) and Unix domain
socket based listeners are supported.  Listeners may also be
disabled.

Binding the http listener to TCP addresses other than 127.0.0.1 or
::1 is deprecated.

The deployment now uses https health checks.  The supervisor is
always able to complete a TLS connection with the use of a bootstrap
certificate that is signed by an in-memory certificate authority.

To support sidecar containers used by service meshes, Unix domain
socket based listeners include ACLs that allow writes to the socket
file from any runAsUser specified in the pod's containers.

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

Split out kube-cert-agent service account and bindings.
Followup on the previous comment to split apart the ServiceAccount of the kube-cert-agent and the main concierge pod. This is a bit cleaner and ensures that in testing our main Concierge pod never requires any privileged permissions.

Run kube-cert-agent pod as Concierge ServiceAccount.
Since 0dfb3e95c5, we no longer directly create the kube-cert-agent Pod, so our "use"
permission on PodSecurityPolicies no longer has the intended effect. Since the deployments controller is now the
one creating pods for us, we need to get the permission on the PodSpec of the target pod instead, which we do somewhat
simply by using the same service account as the main Concierge pods.

We still set `automountServiceAccountToken: false`, so this should not actually give any useful permissions to the
agent pod when running.

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.

Add WhoAmIRequest Aggregated Virtual REST API
This change adds a new virtual aggregated API that can be used by
any user to echo back who they are currently authenticated as.  This
has general utility to end users and can be used in tests to
validate if authentication was successful.

efe1fa89fe Allow multiple Pinnipeds to work on same cluster
Yes, this is a huge commit.

The middleware allows you to customize the API groups of all of the
*.pinniped.dev API groups.

Some notes about other small things in this commit:
- We removed the internal/client package in favor of pkg/conciergeclient. The
  two packages do basically the same thing. I don't think we use the former
  anymore.
- We re-enabled cluster-scoped owner assertions in the integration tests.
  This code was added in internal/ownerref. See a0546942 for when this
  assertion was removed.
- Note: the middlware code is in charge of restoring the GV of a request object,
  so we should never need to write mutations that do that.
- We updated the supervisor secret generation to no longer manually set an owner
  reference to the deployment since the middleware code now does this. I think we
  still need some way to make an initial event for the secret generator
  controller, which involves knowing the namespace and the name of the generated
  secret, so I still wired the deployment through. We could use a namespace/name
  tuple here, but I was lazy.
