Post-deployment patch was not applied on a sidekiq cluster

A new sidekiq cluster was added in December which ended up not getting incorporated into the post-deployment patcher. This resulted in a patch being missed

corrective actions

• Deploy to all sidekiqs instead of individual clusters: https://ops.gitlab.net/gitlab-com/gl-infra/patcher/merge_requests/40
• Validate patches after they have been applied: https://gitlab.com/gitlab-org/release/framework/issues/95
• Patch auditing: https://gitlab.com/gitlab-org/release/framework/issues/138
