Add a new runner to test end-to-end fast data path
This runner caters testing fast host data path (e.g. SRIOV) plus fast VM data path (VM running pktgen-dpdk). It is implemented as a new flavor of the existing Iteration runner. (1) Add a new SLA action rate-control (2) While the SLA target is not met, reduce packet rate until packet loss target is met.
