openvswitch: Allow matching on conntrack label
Allow matching and setting the ct_label field. As with ct_mark, this is populated by executing the CT action. The label field may be modified by specifying a label and mask nested under the CT action. It is stored as metadata attached to the connection. Label modification occurs after lookup, and will only persist when the conntrack entry is committed by providing the COMMIT flag to the CT action. Labels are currently fixed to 128 bits in size.
