What this PR does / why we need it:
Recently, we encountered performance issues with large cardinality data-sets (reproducible with 50 quests, 900 tasks, 900 beacons, 300 hosts). This was due to the N+1 Query Problem. We had thought that EntGo would solve this issue for us, but as it turns out, we had to manually call
CollectFields
on each of our root level queries in order to enable eager-loading. We also updated the test data in order to create a large enough dataset to reproduce the issue.
