    oidc: add discovery document support

    The OpenID Connect specifies that all providers must return a JSON
    discovery document [1] in a well-known location. We can let the user
    pass this document instead of the individual endpoints (i.e. token and
    authorization endpoint). Moreover, we can also check if the requested
    grant_type (implicit to the used plugin, and one of client_credentials,
    password, authorization_code) is supported by the provider before
    starting the auth flow.
