Medium: Tools: crm: add extra flag to CibObject for invalid objects
Background: When processing a CibObjectSet object, it may happen
that some dependencies (constraints) get removed and the
CibObjectSet doesn't know about it. So, on each object remove we
set invalid to True and then check this in
CibObjectSet.recreate_obj_list().
