Draft: Test BBM - DO NOT MERGE
What does this MR do and why?
This is a test MR to help solving gitlab-org/database-team/gitlab-com-database-testing#43 (closed).
The idea is that this MR generates a lot of "noise" of mostly-alike queries with varying numbers of parameters in a WHERE IN
clause. First we will run the db-testing pipeline with master to generate one of the problematic comments, then we will run the db-testing pipeline with new code to collapse the queries.
