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.

cec9f3c4d7 Improve the selectors of Deployments and Services
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.

deploy: wire API group suffix through YTT templates
I didn't advertise this feature in the deploy README's since (hopefully) not
many people will want to use it?

Add YTT template value for setting log level
This is helpful for us, amongst other users, because we want to enable "debug"
logging whenever we deploy components for testing.

See a5643e3 for addition of log level.

1301018655 Support installing concierge and supervisor into existing namespace
- New optional ytt value called `into_namespace` means install into that
  preexisting namespace rather than creating a new namespace for each app
- Also ensure that every resource that is created statically by our yaml
  at install-time by either app is labeled consistently
- Also support adding custom labels to all of those resources from a
  new ytt value called `custom_labels`
