feat(instances): the address search finds a VM by its MAC address too

Browse source 
The "Find IP" dialog takes a MAC address (aa:bb:..., aa-bb-... or
aabb...) as well as an IP address or a network. A MAC finds the VMs with
a network card of that MAC, shut-off ones too (from their definitions),
with that card's addresses when the VM runs: for a MAC seen on a switch
port or in an external DHCP server's log. A MAC on more than one VM is
marked as a possible conflict. Only the VMs with that MAC are read, and
the card's link-local address, which comes from the MAC, is left out.
