Responds to a request for user or item cluster info, depending on the value of isUser(). When serving user clusters, it responds to GET request to /user/clusters/count or /user/clusters/[n], where n is a cluster number. It responds to analogous requests to /item/* for items.

Outputs IDs in CSV or JSON format. When outputting CSV, one ID is written per line. When outputting JSON, the output is an array of IDs.

This is only supported in distributed mode, and when computing clusters in the Computation Layer.
