Implement lookup of permissions for API keys #35970
Conversation
This change implements a lookup of permissions for API keys when a request moves to authorization. In order to support this, the authentication of an API key will attach values as metadata on the authentication result. The values attached will include the source of the role descriptors. The authentication service will then copy this metadata to the authentication object and set the authentication type to API_KEY. The authorization service will use the authentication type to make a decision on how the roles should be obtained.

Is it worth adding ANONYMOUS as an option here?
I think the current behaviour will treat it as REALM which isn't quite right.
Happy to see it in a follow up PR.

Yeah it is. I think there can be some other values as well. Will address in a followup

I see this as caching the built role similar to what we do in CompositeRolesStore (roleCache where we cache the role against the set of role names). But here we are keeping it in the ThreadContext as transient, I was wondering if it would be helpful to or desirable to have a cache similar to what we have in CompositeRolesStore?
We can enhance this if required in next PRs.

As we discussed, this is not equivalent to caching and caching is superior so we'll want to do that.
This change builds upon the work done in elastic#35970 and adds appropriate types for anonymous and internal authentication to the `AuthenticationType` enum.
