Avoid storing Public Key Credential ID onto UserModel #25
Description
It seems not appropriate that I store Public Key Credential ID onto UserModel as its attribute.
It might be better that this ID be not editable on the admin console (might be invisible by some setting...).
On Authentication, I need to retrieve this public key credential ID because it must be set in PublicKeyCredentialRequestOptions.allowedCredentials in navigator.credentials.get() for some types of authenticators (especially, ResidentKey not supported authenticator).
According to Managing multi-factor authentication and Step-up authentication in Keycloak Design proposal for KEYCLOAK-9694, it treats refactored credentials that encompasses accommodating multiple credentials. After realizing it, I will set Public Key Credential Id onto a field of refactored credential which can be retrieved.
At that time before realizing it, Public Key Credential ID is still put onto UserModel.
