Upgrade FunctionJob retrieval endpoints for higher speed

[JavierGOrdonnez]

Right now a JobCollection contains a list of Job uids, which we are retrieving one by one through the get_job endpoint.

It would probably speed up things to be able to use the list_jobs endpoint with a jobCollectionUid option to filter (similar to the already-implemented functionUid filtering option). This endpoint already has pagination included.

To test:
function_id: 9c725f08-34f0-423d-be04-760520aa29d1
function_job_collection_id: ad20b0d6-a331-4caa-8fde-8c2d16cfad8d
