    (Re)start caching scheduler after starting computes in tests

    This moves the scheduler restart logic from the heal_allocations
    tests into a more generic location (like restart_compute_service)
    so that we can re-use it in other functional tests that rely on
    the caching scheduler. There are a couple of other tests that don't
    need to restart the scheduler if we just move the start of the
    scheduler to after we start the computes.
