Pagination request. To determine which edges to return, the connection
evaluates the `before` and `after` cursors (if given) to filter the
edges, then evaluates `first`/`last` to slice the edges (only include a
value for either `first` or `last`, not both). If all fields are null,
by default will return a page with the first 30 elements.
