Description

Follow-up to a discuss issue: https://discuss.elastic.co/t/to-get-end-date-of-week-in-date-histogram/116591/2

Displaying the value range that each histogram bar maps to can be problematic for the last bar of the histogram, since the histogram doesn't give the key that the next bucket would have. Is it something we should look into adding to the response?

Contributor guide

Research direction
Investigate the current histogram bucket response structure and propose an implementation for adding 'from' and 'to' fields to each bucket. Look at existing aggregation code in the search/aggregations/bucket/histogram package.
