ofp-actions: Add clone action.
This patch adds OpenFlow clone action with syntax as below:
"clone([action][,action...])". The clone() action makes a copy of the
current packet and executes the list of actions against the packet,
without affecting the packet after the "clone(...)" action. In other
word, the packet before the clone() and after the clone() is the same,
no matter what actions executed inside the clone().
Use case 1:
Set different fields and output to different ports without unset
actions=
clone(mod_dl_src:<mac1>, output:1), clone(mod_dl_dst:<mac2>, output:2), output:3
Since each clone() has independent packet, output:1 has only dl_src modified,
output:2 has only dl_dst modified, output:3 has original packet.
Similar to case1
actions=
push_vlan(...), output:2, pop_vlan, push_vlan(...), output:3
can be changed to
actions=
clone(push_vlan(...), output:2),clone(push_vlan(...), output:3)
without having to add pop_vlan.
case 2: resubmit to another table without worrying packet being modified
actions=clone(resubmit(1,2)), ...

[blp@ovn.org revised this to omit the "sample" action]
