make the system:authenticated group adder smarter
Fixes#42437
This prevents the group adder from adding the system:authenticated group when:
1. it's already in the list
2. the user is system:anonymous
3. system:unauthenticated is in the list
Smaller alternative to https://github.com/kubernetes/kubernetes/pull/42421 for 1.6.

If a user attempts to use basic auth, and the username/password combination
is rejected, the authenticator should return an error. This distinguishes
requests that did not provide username/passwrod (and are unauthenticated
without error) from ones that attempted to, and failed.

apiserver command line options lead to config
Logically command line options lead to config, not the other way around. We're clean enough now we can actually do the inversion.
WIP because I have some test cycles to fix, but this is all the meat.
