This is the first of a few related changes that re-organize our API after the big recent changes that introduced the supervisor component.
Signed-off-by: Matt Moyer <moyerm@vmware.com>
- 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`
- Also continue renaming things related to the concierge app
- Enhance the uninstall test to also test uninstalling the supervisor
and local-user-authenticator apps
