  1. Fix tree spawn routed component issue 

     * Fix open-mpi#6618
   - See comments on Issue open-mpi#6618 for finer details.
 * The `plm/rsh` component uses the highest priority `routed` component
   to construct the launch tree. The remote orted's will activate all
   available `routed` components when updating routes. This allows the
   opportunity for the parent vpid on the remote `orted` to not match
   that which was expected in the tree launch. The result is that the
   remote orted tries to contact their parent with the wrong contact
   information and orted wireup will fail.
 * This fix forces the orteds to use the same `routed` component as
   the HNP used when contructing the tree, if tree launch is enabled.
