Title: Track node gets and puts with a spiral stat

When using the `slide_uniform` sample type for the node puts / gets
histogram, the one minute count will be inaccurate for very small
and somewhat large numbers of readings. `Folsom` (actually `bear`)
only calculates the histogram when there are 5 or more readings.
The `slide_uniform` sample type holds a maximum number of 1028
readings per second by default, so nodes with greater throughput
than that will show lower than actual one minute counts. Using
`spiral` for the get / put count solves these issues.
