Description

Technical debt/behind the scenes improvement.

Salt 2014.1 introduced new salt/presence events from the master, which purport to give a regular update on which minions are in touch with that master. I think they added it for their halite UI.

This could be simpler than the "xxx is late reporting in" checks we currently do. We would need to check exactly how salt is determining the presence of a minion though, and see whether it is well behaved (this is brand new code in an upstream project so can't assume it just works).
