Improvements for working with large issues, merge requests, etc.

Problem Description

A simple query which would've returned 3 results, we are rejected:

result exceeds maximum length of 1048576

I think we need something to parse the data that was collected and figure out how to present it to the client.

To do

• Limit number of responses to be returned
  • Issues
  • Merge requests
  • User events
• Allow control over which fields are returned
  • Issues
  • Merge requests
• Limit the description length so the response fits into the maximum response size
  • Issues
  • Merge requests
