Aaron U'Ren 944ab91725 fix(FoU): make more robust
FoU implementation now properly handles a whole host of things:

* It now actually handles IPv6 by changing the encapsulation protocol to
  GUE instead of generic FoU. I worked with generic FoU tunnels for
  several days and could get it to support IPv4 and IPv6 at all even
  when placing using it with the IPv6 proto and with iproute2 in IPv6
  mode (-6)
* It now handles converting between the two tunnel types seemlessly and
  without leaving legacy tunnel artifacts behind. Previously, you could
  change the encap type but it wouldn't change the tunnels
* Abstracted constants
