this seems unrelated to the PR being backported?

Bug: Unrelated change included in backport PR
The removal of the commented # @skip(cluster=False) decorator from test_active_io_threads_stats is unrelated to the purpose of this backport PR (adding active_worker_threads metric). This was flagged by a reviewer in the PR discussion as "unrelated to the PR being backported" and likely shouldn't be included in this change.
