    Ensure no OVN orphaned members remain on upgrade
    
    During OS upgrade/redeployment members are being re-added to the
    cluster with the new UIDs. While this is expected behavior, as all other
    identification is being wiped, this process leave orphaned members
    in raft cluster. With some time this may result in unexpected behavior
    as unreachable orphaned nodes may outnumber valid cluster members in
    quorum.
    
    This patch proposed to drop any members with matching IP in the cluster,
    except (self) right after the node is re-joined to the cluster.
