Add worker-handoff node
worker-handoff node is universal node which taakes packets
from the input node and hands them over to worker threads.
Currently it supports flow hashing based on ipv4, ipv6 and
mpls headers.
New cli:
set interface handoff <intrerface-name> workers <list>
e.g.
set interface handoff TenGigabitEthernet2/0/0 workers 3-6,9-10
