We need only a subset of the NM bearer features so it would be ok to
replace or patch to limit its behavior.

What we need is existing QNAM instances to not fall dead if user is on
3G + wifi and then disables wifi, or alternatively if on 3G and wifi
gets enabled the connections should migrate to wifi. I don't know if
connectivity-api currently has what would be needed for the bearer.

We do not need network controlling in bearer since indicator-network
handles that.

Bug description:
  Krillin, rc-proposed, r83

  
  DESCRIPTION:
  I've been trying to track down the cause of the occasional UI freezes on my Krillin device, and I noticed that whenever the UI freezes for 2-4 seconds, I get a burst of "PropertiesChanged" signals in dbus-monitor

  Here's a log of what's shown in dbus-monitor:
  http://pastebin.ubuntu.com/11992322/

  I'd guess the problem is in the code that actually catches the signals
  and acts accordingly.

  HOW TO REPRODUCE: 
  1) Move to a place where many wifi hotspots are available
  2) Connect the device via USB and run "phablet-shell" and then "dbus-monitor"
  3) Use the device while keeping an eye on dbus-monitor output
