Have integration tests run with both scheduler and job queue (#6787)

* Move integration tests to separate directory

This commit moves all integration tests (the ones marked with pytest.mark.integration_tests atleast) to a new directory tests/integration_tests.

* Have integration tests run with both queue and scheduler

This commits adds the pytest.mark.scheduler mark and scheduler fixture to some of the integration tests, so that they will be ran with both the scheduler and job queue.

* Move pytest snapshots down one level
