Using extend Destination list in the FTE to implement the mirroring
feature.
Add two new rdma-core command for create group action and multiple
destination action.
Group action which is a group of sub-action will be used together
for input to multiple destination action.
Multiple destination action can be used for mirroring packet to
different vport or Queue.
