ovn-controller: Always monitor all logical datapath groups.

Always monitor all logical datapath groups. Otherwise, DPG updates may
be received *after* the lflows using it are seen by ovn-controller.
Since the number of DPGs are relatively small, we monitor all DPGs to
avoid the unnecessarily extra control plane round trip for the lflows to
be processed.
