performance-metrics: Start VMs with the same IP in a unique IP range

Browse Source 
Performance tests are expected to be executed sequentially, so we can
start VM guests with the same IP while putting them on a different
private network. The default constructor "Guest::new()" does not work
well, as we can easily create more than 256 VMs from repeating various
performance tests dozens times in a single run.
