Title: Add host_ip_addr parameter and use it for spice tests (migration).

Spice client is connecting directly to a host which hosts displayed VM and is informed about upcoming migration with qemu monitor command which has a parameter - host IP of destination host.
When doing single host migration spice client may not be running on the host but on another VM (Spice tests scenario) that's why we need the IP of host where spice client needs to be reconnected.

That's why adding host_ip_addr parameter and using it for migration and spice tests. If the value is not provided taking IP address on interface specified in netdst param (good enough in simple host network configuration).
