delete old airbyte prod databases

[fatchat]

we gave airbyte its own rds in 2024-01 and its old databases still exist on ddp-production

the databases

• airbyte2
• temporal
• temporal_visibility need to be deleted from ddp-production

they need to be deleted by the ddpairbyte user which is the owner, after which the role ddpairbyte should also be deleted

the airbyte2 database has open connections from ddpmon which is used by prometheus. these need to be killed somehow
