* handle disconnects like core device address changes and do a
disconnect/connect iteration
* after connection failure wait 10 seconds and try again
* this addresses the slight regression from release-2
to release-3 where the moninj protocol was made stateful
(#838 and #1125)
* it would be much better to fix smoltcp/runtime to no loose the
connection under pressure (#1125)
* the crashes reported in #838 look more like a race condition
* master disconnects still require dashboard restarts
