Add Usage data tracking using Redis HLL for UI events for non-authenticated events
As a follow-up issue from discussions ttps://gitlab.com/gitlab-org/gitlab/-/merge_requests/41301
With !41301 (merged) we add API call to increment unique values for authenticated users.
We might consider having this also for non-authenticated users.
