trunk: Add tempest test validating subport connectivity

The patch uses commands over SSH to define VLAN interfaces within
guests.

Test creates two instances with one trunk port and one subport - each
port is on different network. Connectivity is tested
using ping from one instance to the addresses on VLAN interfaces of the
other instance.
