VPP_Device - add baseline tests - part IIa)

CSIT-1372

Add following baseline tests to VPP_Device:
- ip4
  eth2p-ethip4-ip4base-eth-2vhost-1vm-dev

- ip6
  eth2p-ethip6-ip6base-eth-2vhost-1vm-dev

- l2bd
  eth2p-eth-l2bdbasemaclrn-eth-2vhost-1vm-dev

- l2xc
  eth2p-eth-l2xcbase-eth-2vhost-1vm-dev

+ fix doc strings in all vpp_device tests
