Description

The Pager API is exactly what one's need to fetch a list of Records.

However on time to time you wish to update the list, and it would be nice to be able to use the ETag to refresh the list without reloading the whole collection.

My understanding is that the Pager object is not far from being able to handle that.

Contributor guide

Research direction
Understand the current Pager implementation and how ETag headers are handled in the Kinto API. Then modify the Pager to accept an optional ETag and perform a conditional request to refresh the list.
