[feat] Create resources for tt: format, state and event

[majorbruteforce]

• Create independent entities TTFormats, TTStates and TTEvents under base path /tt
• The following additional endpoints are expected :
  • GET /:matchId/state : To fetch the latest match state
  • GET /:matchId/event?id=previousEventId : To fetch the most recent event next to the passed event (get most recent if nothing is passed)
  • GET /:matchId/event-series?id=previousEventId : To fetch all the events for the match sorted in descending order of time after the event with id previousEventId. (get all if nothing is passed)
  • POST /:matchId/event : To post a new event.
  • PATCH /event/:eventId : To patch a created event
  • DELETE /event/:eventId : To delete a created event

NOTE: Comment the schema for the three entities in the same thread.
