[IOCOM-1178] FIMS OIdC flow

[Vangaorth]

Short description

This PR adds a fake OIdC flow for FIMS, with both Relying Party and Provider support.

List of changes proposed in this pull request

• relyingParty router that:
  • redirects to provider
  • handles the redirection router, checking for mandatory parameters (like nonce, state and lollipop-headers presence)
  • decodes and shows the signed idToken to display fake citizen informations
• provider router that:
  • handles the OIdC flows, with proper and mandatory parameters
  • supports both Authorisation Code flow and Implicit Code Flow, like the real provider
  • sets and validates cookies, like the real provider (even the FIMS authorizasion cookie)
  • signs and generate the idToken
  • simulates the Fast Login expiration
• history endpoint that generates and handles a fake paginated access history and simulates its export

All of the above is configurable with the config.ts file

How to test

Start the dev-server and type http://localhost:3000/fims/relyingParty/1/landingPage in your web-browser (or use something like cUrl to follow such link)
