 Currently presence service detects whether we become connected by finding
 the IPv4 address of interfaces when network manager brings them up.

 We also publish this IPv4 address as a buddy property in salut and gabble,
 so that theoretically activities which aren't using tubes can make direct
 connections to each other. To the best of my awareness, there are no such
 activities, and we should not rely on IPv4 connectivity for anything.

 So, we should stop doing both of these things, and just use more general
 connectivity indications from network manager to decide when it's worth
 trying to connect in presence service (basically, do we try to connect
 with gabble or not).
