Title:
  users should define wifi net preference, defaulting to heuristics

Status in NetworkManager:
  Confirmed
Status in network-manager package in Ubuntu:
  Triaged

Bug description:
  I'm at a hotel.  There's a strong network AP in this room that my org
  owns, and a weaker hotel wifi AP elsewhere.

  Before my org convened, I connected to the hotel wifi, so it's in the
  list of SSIDs that I automatically connect to.  I would rather connect
  to my org's wifi in almost all cases. But, that doesn't happen, and it
  connects to the unwanted hotel Wifi AP.  I should be able to order the
  SSIDs that I will automatically connect to my dragging them in the
  list and a lower network should never be used if a higher is
  available.

  So, in picking a network to connect to, we should try each in order of
  user-defined preference and abandon any that are below some threshold
  of usefulness.

  Additionally, if nothing more-preferred is available, pick among
  crypto'd networks, abandoning too weak.

  Then pick according to strength if everything else is equal.

  I describe best in code...

  order_of_preference = sorted(((net.user_defined_order if net.strength
  > epsilon else INFINITY), (0 if net.has_crypto else 1), net.strength,
  net) for net in network_list)

  net_to_use = order_of_preference[0][3]

  <https://wiki.ubuntu.com/Networking#previous-networks>: "When
  reprioritization of networks has been implemented in NetworkManager,
  pressing on a network should make it draggable so that you can reorder
  the list (bug 1538972)."
