    [placement] Require at least one resource class in allocation

    If an allocation was made with an empty resources object, a 500 response
    code would result. This change adjusts the schema to use minProperties
    of 1 to say there must be at least one resource class and value pair in
    the allocation. If there is not a 400 response is returned.

    As this is fixing 500 response to a useful error, no microversion is
    required. A previous gabbi file which demonstrated the problem has been
    updated to demonstrate that the problem has been fixed.
