s4:provision - use the new "interface_ips" python call to detect the right host IPv4 address

Inform the user when there are more possibilities (so he can check for the
right address and otherwise he is able to do an immediate reprovision) and no
possibility at all (then we fall back to the loopback address "127.0.0.1" - this
is thought for testing purposes).

I think this should be enough for closing bug #5484.
