nova.scheduler.filters.utils is tested in two separate files

[Ming Yang]

Two separate tests [nova/tests/unit/scheduler/test_filters_utils.py] and [nova/tests/unit/scheduler/filters/test_utils.py] appear to be testing methods of the same file [nova/scheduler/filters/utils.py] in a very similar fashion. They should be consolidated.

    Consolidates scheduler utils tests into a single file.

    Two separate test files [nova/tests/unit/scheduler/test_filters_utils.py] and
    [nova/tests/unit/scheduler/filters/test_utils.py] appear to be testing methods
    from the same module nova.scheduler.filters.utils in a very similar fashion.

    Additional cleanup:
    * Removed superfluous directory [nova/tests/unit/functional]
