app/testpmd: support NVGRE encap as sample action

Browse Source 
Add support for rte_flow_action_nvge_encap as a sample action.

The example of test-pmd command:

1.  set nvgre ip-version ... tni ... ip-src ... ip-dst ...
    set raw_encap 1 eth src... / ipv4... /...
    set sample_actions 2 nvgre / port_id id 0 / end
    flow create 0 ... pattern eth / end actions
       sample ratio 1 index 2 / raw_encap index 1 / port_id id 0...

    The flow will result in all the matched egress packets will be
    encapsulated and sent to wire, and also mirrored the packets
    using NVGRE encapsulation data and sent to wire.
