Update config documentation

**Feature request**
It would be great to have pagination for data.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_pagination` with default `false`.

Start by locating the configuration handling and the data output entry points in the terminal agent. Confirm how production data is currently returned, then define the pagination behavior and verify that enable_pagination defaults to false while enabling pagination when set to true.
