This file was responsible for logging
Web IDE commits.

This commit is also responsible for removing the
IDE feature flag entirely

Add `members` because MR approver suggestion
needs to display non-members too.
Rename `users` to `raw_users` for clarity.

Add reader for whether code owner is defined,
which is used to decide whether to display tips.

This makes a temporary implementation of the
Web IDE commits counter using Redis while
https://gitlab.com/gitlab-org/gitlab-ce/issues/52096
is being discussed further for a more generic
approach to counters

Implements UsageCounters model to track feature usage counters
and makes easy to extend for future counters
