Spread CI minute reset workers over 8 hours instead of 3 hours
As part of Monthly run of ClearSharedRunnersMinutesWorker
causes burden on gitlab.com database servers, we've tried to spread the CI minute reset workers over 3 hours for the 2020-12-01 run but as this dashboard shows, we still have SLA drop to below 60% during the run. This issue is to extend the existing code and spread the CI minute reset workers over 8 hours instead of 3 hours (currently).
The 2020-12-01 run also caused another incident as documented: gitlab-com/gl-infra/production#3101 (closed)
The goal of this issue to is to have this MR completed by the 2021-01-01 run
