feat(op): implicit consent for internal rp

[lucacavallaro]

List of changes

1. Add a new, optional metadata for Client called is_internal (Boolean). Setting is_internal to true means that the external web services referenced by the client metadata (via redirect_uri) is managed by PagoPA S.p.A.
2. Authentication Requests originated by internal clients no longer require explicit consent by the citizen.

Motivation and context

Internal client does not need an explicit consent by the citizen cause the data will not be shared with third parties.
