Add supported token provider declarations

When retrieving a credential or hint, it may be possible to
provide an "upgrade" to an ID token based authentication.
In order to do this, a client must declare which OpenID Connect
providers it supports, and provide client / token provider specific
configuration parameters for each if necessary.
