[spice v1 6/8] tests: migrate: add option for hostname change

[Victor Toso <victortoso@xxxxxxxxxx>]

From: Victor Toso <me@xxxxxxxxxxxxxx>

This is used in the migrate message and being able to tweak it allows
clients from different machines to test this local migration test.

Example of usage:
    ./migrate.py --hostname 192.168.122.1 --wait-user-connect

In a VM with access to 192.168.122.1:
    remote-viewer spice://192.168.122.1:5911
