auto test: increase sleep (#4282)

Doing a reload every 10ms and sleeping 10ms makes this too racy,
increase all those sleeps to 5ms. A better method would be to get
notified of the reload/change, this would require some polling to get
the RR we expect, with a much longer timeout to stop the test
eventually.
