        Checks if the collection contains only the given allowed items. list may contain zero to max(allowedItems) items from allowedItems.

        Examples:
        containsOnly(Arrays.asList(new Integer[] { 1, 2, 3 })) --> true
        containsOnly(Arrays.asList(new Integer[] { 1, 2, 3 }), 1, 2) --> false, 3 missing
        containsOnly(Arrays.asList(new Integer[] { 1, 2, 3 }), 1, 99) --> false, 3 missing
