Description

Scrubs are being reported to be very slow in multiple teuthology tests causing them to fail.
An example: https://pulpito.ceph.com/dis-2023-05-09_11:02:54-rbd-wip-dis-testing-distro-default-smithi/7268117/

This issue has been showing up after changes made in the mClock scheduler code here: https://github.com/ceph/ceph/pull/49975/files
Similar to the recovery fix in the PR mentioned, we need to reduce scrub cost as well so that they are not severely throttled.
