[cparratto]

Adds bucket duration as configurable element for rolling summaries.

I would like to be able to configure these values. Happy to make any other changes required to get this upstream

I'll take a look at this in the next day or two.

If we're going to expose the configuration of rolling summaries, we need to expose both the number of buckets as well as the bucket width.

Sounds good. I will add this to the PR now.
