Proof-of-concept implementation of a potential new Supervisor feature
which allows arbitrary upstream ID token claims to be mapped into a
new top-level claim in the ID tokens issued by the Supervisor.
This commit is a WIP commit because it doesn't include many tests
for the new feature.

Where possible, use securityContext settings which will work with the
most restrictive Pod Security Admission policy level (as of Kube 1.25).
Where privileged containers are needed, use the namespace-level
annotation to allow them.
Also adjust some integration tests to make similar changes to allow the
integration tests to pass on test clusters which use restricted PSAs.
The following validation is enforced:
1. Names must start with client.oauth.pinniped.dev-
2. Redirect URIs must start with https://
or http://127.0.0.1
or http://::1
3. All spec lists must not have duplicates
Added an integration test to assert all static validations.

- 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
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
- Note that v0.8.0 no longer supports the "trivialVersions=true"
command-line option, so remove that from update-codegen.sh.
It doesn't seem to impact the output (our generated CRD yaml files).
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.

This makes it so that our service selector will match exactly the
YAML we specify instead of including an extra "kapp.k14s.io/app" key.
This will take us closer to the standard kubectl behavior which is
desirable since we want to avoid future bugs that only manifest when
kapp is not used.

Fixes#801. The solution is complicated by the fact that the Selector
field of Deployments is immutable. It would have been easy to just
make the Selectors of the main Concierge Deployment, the Kube cert agent
Deployment, and the various Services use more specific labels, but
that would break upgrades. Instead, we make the Pod template labels and
the Service selectors more specific, because those not immutable, and
then handle the Deployment selectors in a special way.
For the main Concierge and Supervisor Deployments, we cannot change
their selectors, so they remain "app: app_name", and we make other
changes to ensure that only the intended pods are selected. We keep the
original "app" label on those pods and remove the "app" label from the
pods of the Kube cert agent Deployment. By removing it from the Kube
cert agent pods, there is no longer any chance that they will
accidentally get selected by the main Concierge Deployment.
For the Kube cert agent Deployment, we can change the immutable selector
by deleting and recreating the Deployment. The new selector uses only
the unique label that has always been applied to the pods of that
deployment. Upon recreation, these pods no longer have the "app" label,
so they will not be selected by the main Concierge Deployment's
selector.
The selector of all Services have been updated to use new labels to
more specifically target the intended pods. For the Concierge Services,
this will prevent them from accidentally including the Kube cert agent
pods. For the Supervisor Services, we follow the same convention just
to be consistent and to help future-proof the Supervisor app in case it
ever has a second Deployment added to it.
The selector of the auto-created impersonation proxy Service was
also previously using the "app" label. There is no change to this
Service because that label will now select the correct pods, since
the Kube cert agent pods no longer have that label. It would be possible
to update that selector to use the new more specific label, but then we
would need to invent a way to pass that label into the controller, so
it seemed like more work than was justified.
These fields were changed as a minor hardening attempt when we switched to Distroless, but I bungled the field names and we never noticed because Kapp doesn't apply API validations.
This change fixes the field names so they act as was originally intended. We should also follow up with a change that validates all of our installation manifest in CI.

- Change list of attributeParsingOverrides to a map
- Add unit test for sAMAccountName as group name without the override
- Change some comments in the the type definition.
This change updates the default NO_PROXY for the supervisor to not
proxy requests to the Kubernetes API and other Kubernetes endpoints
such as Kubernetes services.
It also adds https_proxy and no_proxy settings for the concierge
with the same default.
