Currently, `PhabricatorMySQLSetupCheck` runs only on the `w` mode connection: - This fails in read-only mode (shortly worked around). - Instead, every replica should be checked individually.

Currently, `PhabricatorMySQLSetupCheck` runs only on the `w` mode connection: - This fails in read-only mode (shortly worked around). - Instead, every replica should be checked individually. More fundamentally `PhabricatorDatabaseSetupCheck` runs explicitly against only the non-cluster connection. - This fails to detect total failure of cluster configuration. - Instead, it should be aware of cluster configuration.
