Merge pull request #77 from opentechinstitute/commotion-feed-16

Tested and confirmed working. Flashed a node, configured it, ssh'd in and issued: servald id self
Then reflashed with sysupgrade image, repeated config & checked servald id self. A different serval key was created on each node flash.
