remove rbac super user
Cleaning up cruft and duplicated capabilities as we transition from RBAC alpha to beta. In 1.5, we added a secured loopback connection based on the `system:masters` group name. `system:masters` have full power in the API, so the RBAC super user is superfluous.
The flag will stay in place so that the process can still launch, but it will be disconnected.

add rbac action to subjects type
This adds the ability to go from an authorization action to the list subjects who have the power to perform the action. This will be used to either back an RBAC specific endpoint or generic authorization endpoint. Because of the way authorization works today, the set of subjects returned will always be a subset of those with access since any authorizer can say yes.

add controller roles
Upstream controller roles that have downstream.
@sttts this is a start at roles for controllers. I've made names match for now, but they could use some love in both the controller manager and here. I'd recommend using this as a starting point.
Before this change, Authorize() method was just returning an error,
regardless of whether the user is unauthorized or whether there
is some other unrelated error. Returning boolean with information
about user authorization and error (which should be unrelated to
the authorization) separately will make it easier to debug.
Fixes#27974
