Alerts for Wiki Replicas hosts (`clouddb*`) are currently routed to the `data-persistence` team together with the alerts for production hosts (`db*`).
Alerts are defined in https://gerrit.wikimedia.org/r/plugins/gitiles/operations/alerts/+/master/team-data-persistence
Replication lag alerts were disabled for clouddb hosts in https://gerrit.wikimedia.org/r/c/operations/alerts/+/835117, by filtering based on `job: mysql-core`.
We should instead route all the alerts (including the ones for replication lag) to `team=wmcs` if `job: mysql-labs`.
Open questions:
* Sanitariums also are tagged with `job: mysql-labs`, should they be tagged with `job: mysql-core` instead?
* clouddbs are currently getting tagged with `cluster: mysql` in [hieradata/regex.yaml](https://gerrit.wikimedia.org/g/operations/puppet/+/84300b2dae09155da61082b8fc9aa7d73901542a/hieradata/regex.yaml), should they be tagged with `cluster: wmcs` instead? This would include them in the WMCS [NodeDown alerts](https://gerrit.wikimedia.org/g/operations/alerts/+/e6e49afde295b1b396c507f1e4ee30258df037a7/team-wmcs/general_nodes_down.yaml).
