Remove unused IssuesChannel

With 
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/59958 
in production, we no longer need this code.

There's no impact to the user since the same feature is
now implemented using GraphQL subscriptions.

Merge branch '273322-fy21q4-foundations-kr2-audit-and-update-buttons-on-projects-tagscontroller-index' into 'master'

Audit and update buttons on Projects::TagsController#index"

See merge request gitlab-org/gitlab!61413

Flush statistics cache anytime it is updated

See merge request gitlab-org/gitlab!52938

`Projects::UpdateStatisticsService` attempts to refresh project
statistics, but it relies the caller to flush the existing statistics
cache for the repository. If the flush doesn't happen, the refresh won't
actually do anything. For example, this might be happening in
`ProjectCacheWorker`.

We now expire the stats inside the service to ensure consistent results.

This came out of
https://gitlab.com/gitlab-org/gitlab/-/issues/255001.
