This PR adds a new hook for parallel testing which is executed before running the migrations.
Why
We have a quite big test database and we are importing a testing database dump after the database is created. We do not use the seeders for performance reasons. As the test dump is not necessarily always up to date, we want to run the migrations afterwards. As the normal hook is called after the migration this is not possible for us.
Therefore we'd like to introduce this hook, which allows us to run the import before the migrations are executed.
