Improve the documentation about the possible parameters of items.iter()

I’m trying to understand the possible parameters of Job.items.iter() but it’s not that clear to me:

• Why is count documented as a parameter on its own? (I assume the rest of the pagination parameters are assumed to be part of apiparameters)
• What is requests_params for?
• I see other parameters mentioned in the documentation that don’t seem part of the Items API, pagination or meta. For example, filter (in the 4th example of the Items documentation, with list instead of iter but I assume they accept the same arguments)

Start with the linked Job.items.iter() API documentation and the Items documentation examples. Compare how count, apiparameters, requests_params, and filter are described, then clarify which parameters are supported and how they relate to pagination and metadata. Done means the parameter documentation and examples consistently answer these questions.
