cubicweb #2919310 Drop support for Web only instance [validation pending]

Wec currently have 3 possibles setup

  • repository
  • all-in-one
  • twisted

the last one , twisted allows a "web only" server that remotly connect to another repository instance. This setup is very seldomly used and there is various evidence it is slightly broken already. I suggest dropping it for now as it will greatly help internal refactoring. This kind of instance may return in the future with a WSGI backend.
