[DEVX-2153] Pagination

[hummusonrails]

Two topics:

"Pagination hidden by default: Pagination is hidden by default but users can drop down to a closer API level client to do manual paging, if the API supports it"

"Sane defaults for pagination: The higher level iterable/cursors should be smart enough to reduce the number of HTTP requests that they make with sane defaults. For example, a paging size of 1 or 100 can be suboptimal, where a paging size of 5 or 10 may be more suitable. This value may change based on the product/endpoint."
