mon: smooth io/recovery stats over longer period

On a busy cluster, the PGMap will turn over every 1-2 seconds and
OSDs will report PG stats every 5-10 seconds.  Averaging over only
two PGMap versions (2-4 seconds) will lead to erratic and spikey
delta values.  Move to 6 versions (6-12 seconds) to better match
the reporting interval while still keeping the values somewhat
responsive.
