            FIXME: the way member IDs are computed can cause collisions!
            Problem: In P4Runtime action profile members, i.e. action buckets,
            are associated to a numeric ID chosen at member insertion time. This
            ID must be unique for the whole action profile (i.e. the group table
            in OpenFlow). In ONOS, GroupBucket doesn't specify any ID.

            Solutions:
            - Change GroupBucket API to force application wanting to perform
            group operations to specify a member id.
            - Maintain state to dynamically allocate/deallocate member IDs, e.g.
            in a dedicated service, or in a P4Runtime Group Provider.

            Hack: Statically derive member ID by combining groupId and position
            of the bucket in the list.
