ProjectCacheWorker via `/api/v4/internal/post_receive` can result in 80k+ Gitaly calls

In certain circumstances, a single /api/v4/internal/post_receive can lead to 80k n + 1 FindCommit Gitaly calls onto the underlying repository from the Sidekiq ProjectCacheWorker job.

This is also leading to the Gitaly Abuse detector alerting on possible abuse (it is not)
