    Enable log_slave_updates

    Without log_slave_updates enabled, the bin logs are only written on the
    cluster server that handles the request. This makes database recovery
    more difficult as the bin logs are spread across all servers and must be
    combined manually in order to recover the database.

    Enabling log_slave_updates ensures all nodes in the cluster contain the
    complete bin logs and recovery can be performed from any cluster member.
