    Fix: PE: Exclude resources and nodes from the symmetric_default constraint in some circumstances
    
    This is particularly relevant to bundles where only specific nodes
    are allowed to a particular resource.  Previously, even if we set the
    tuple up correctly during container_unpack(), common_unpack() would
    re-add the full node set afterwards recursively via the parent.
    
    Similarly, the bundle "nodes" are not eligable for running any other
    resource than the one container_unpack() assigned it and there is no
    reason to add it to their allowed_nodes list.
    
    Keeping the allowed_nodes list concise also ensures crm_resource
    --cleanup does the bare minimum necessary when the resource is in an
    unknown state.
