cubicweb #3489631 automatic testing with postgresql [validation pending]

We should be able to run automated tests using a postgres instead of sqlite backend. That involves:

  1. creating a postgres cluster for the test
  2. starting the server
  3. creating the empty (cached) db
  4. running the tests
  5. stopping the server

With steps 1 and 3 only when needed.
