Modify sweep ping test cases

- Write separate sweep ping test cases for jumbo frames
- Compute sweep ping end size from reported MTU on DUT interface
- Set MTU on TG according to MTU on DUT interface
- Log VPP packet traces on IPv4 and IPv6 tests failure
- Remove VM_ENV tag from sweep ping test cases for jumbo frames
