During node look up sometimes IPA sends hardware inventory information before
the interfaces are up, resulting in empty interfaces information being sent
to the conductor. This causes conductor to throw exceptions and polluting
the log until the real interfaces information is populated. This change makes
IPA to wait for at least one interface to be up before trying for node lookup.
