Add get_node_iface_ips (node_config, iface_name) function.

  Get list of IP address configured on given interface on given node.

  @param: node_config  Pillar node configuration (as dict)
  @param: iface_name   Name of the interface defined in pillar node config
                       OR name of VRF ("vrf_<something>") whichs ifaces are
                       to be examined.
