Tracking ticket voor EB upgrade (PHP/Symphony)

• Rebase upgrade branch onto main @Jong-Vincent

• CI tests runnen in ci/qa/all.sh; eerst main runnen (zou helemaal groen moeten zijn) en daarna voor de branch, zodat we een baseline hebben van wat er fixed moet worden. @johanib

• Fix push from Manage to Engineblock
  The controller for URI "/authentication/idp/single-sign-on" is not callable: Controller "engineblock.controller.authentication.identity_provider" cannot be fetched from the container because it is private. Did you forget to tag the service with "controller.service_arguments"?

• Implement running tests using DevConf

• Research fix or migrate Behat tests
  Check which Behat dependencies can be potentially removed to run integration tests
