Add truncate instruction and support it with PI framework
To support truncate by P4Runtime clone/mirror session, we need to pass the
truncate size/length from ONOS northbound to the southbound.
As discussed in the SDFabric syncup, we decide to pass this information via
the instruction in group bucket so applications or pipeliners can simply
reuse current APIs.
