e2e: virtio: net: add e2e cases for virtio-net

Add e2e cases to test virtio-net connection.
6 cases are added as following:
- virtio_net_ping_test
- virtio_net_ping_test_with_mrg_rxbuf
- vhost_user_net_ping_test
- vhost_user_net_ping_test_with_mrg_rxbuf
- vhost_user_net_ncat_test_with_mrg_rxbuf_guest2host
- vhost_user_net_ncat_test_with_mrg_rxbuf_host2guest

These cases will firstly start a guest vm
with virtio-net device.
First four test following scenarios:
- regular virtio-net without mrg_rxbuf
- regular virtio-net with mrg_rxbuf
- vhost-user-net without mrg_rxbuf
- vhost-user-net with mrg_rxbuf
After vm start, it will configured network in guest,
and then do ping operation in two directions.

Last two test cases will use ncat to
transfer a random file between guest and host via
vhost-user virtio-net with MRG_RXBUF feature.

TEST=tools/run_tests --dut=vm -vv -E \
'package(e2e_tests) & (test(vhost_user_net) | test(virtio_net))'
