    Adding tests to demonstrate bug #1821824

    Fixed functional test test_flavor_traits_based_scheduling as it
    would pass 50% of the times even if the required trait was not
    taken into account by adding a new part that disables the compute
    host that has the required trait and retries, expecting a no valid
    host error.

    Added functional test test_flavor_forbidden_traits_based_scheduling
    to test that forbidden traits are taken into account.

    The second test temporarily passes where it should not until the
    next commit where the bug is actually fixed.
