Re: [webauthn] Indicate resident key credential "preferred" during registration and find out what the authenticator offered (#991)

RP may have active preference for non-RK. 

Christiaan wants it so that PIN doesn't happen as that is where the **_general_** consensus is in FIDO community. But that should not be a absolute requirement, IMO, for the authenticators . An authenticator may want to do always user verification because of security levels or differentiation or whatever.

Another RP may actually want it because, it is creating a bunch of credentials and storage is limited. So he may actually prefer non-RK. But from authenticators side, in some cases, there is no issue with storage or it can't/don't want to do non-resident keys. So we have to allow that also. 

RP wants one variable, which works across all kind of authenticators. Hence the fallback mechanism.
