Moving sqstat back to emery

We moved this to erbium on Jan 30, and recently have been noticing
erratic graphs.  Moving sqstat back here to see if this move was the
cause of the problem.  Also, since we want to replace udp2log with
kafkatee soon, hopefully we will be able to get rid of the lossy
multicast udp2log relay and just rely on Kafka, and then get rid
of emery altogether.
