Once db1115 has been reimaged and cleaned up, we should get orchestrator to start using db1115 instead of db2093 so we can have consistency (eqiad being the writable DC).
@Kormat I will ping you once this can happen.
[] Move orchestrator DB from db2093 to db1115 (enable replication)
[x] Fix `orchstrator_srv` grant on db1115, ensure it works from dborch1001.
[] Stop orchestrator
[] Merge https://gerrit.wikimedia.org/r/c/operations/puppet/+/774485
[] Take a mysqldump of the orchestrator database on db2093: `sudo mysqldump --single-transaction --ssl-verify-server-cert -h db2093.codfw.wmnet --databases orchestrator > orchestrator.dump.T301315`
[] Load dump into the test section: `sudo db-mysql db1124 < orchestrator.dump.T301315`. Double-check that it loads correctly, and that the data looks good.
[] Drop orchestrator database on db2093: `sudo db-mysql db2093 -e 'drop database orchestrator'`
[] Load mysqldump into db1115, with replication enabled: `sudo db-mysql db1115 < orchestrator.dump.T301315`
[] Run puppet on dborch1001, start orchestrator.
[] Reimage db2093 to Bullseye
[] Start to backup orchestrator on db1115
