Support rss action in the sample sub-actions list.

The examples for the sample flow use case and result as below:
set sample_actions 0 mark id  0x12 / rss queues  0 1 2 3 end  / end
flow create 0 ingress group 1 pattern eth / end actions
sample ratio 1 index 0 / jump group 2 / end

This flow will result in all the matched ingress packets will be
jumped to next table, and the each packet will be marked with 0x12
and duplicated to rss queues of the control application.
