features:
- Add support for OVS DPDK pmd auto balance parameters.
This feature adds 3 new role specific THT parameters to set
pmd-auto-lb-load-threshold, pmd-auto-lb-improvement-threshold,
and pmd-auto-lb-rebal-interval in OVS through OvsPmdLoadThreshold,
OvsPmdImprovementThreshold and OvsPmdRebalInterval respectively.
