commit 944f378f59974a7c06ae75a1ef421389b68ef040
Author: Gao,Yan <ygao@suse.com>

Fix: pengine: "symmetrical" defaults to "false" for serialize orders
    
    Practically it has already been the case. But previously it would
    complain if "symmetrical" was not explicitly configured for serialize
    orders with resource sets:
    ```
    Cannot invert serialized constraint set ...
    ```
    
    This commit officially makes "symmetrical" default to "false" for
    serialize orders.
