Adds ability to configure ProxySQL's max replication lag
via configuration value ``proxysql_backend_max_replication_lag``
which is set to default value as per documentation. If it is
greater than 0, ProxySQL will regularly monitor replication lag
and if it goes beyond the configured threshold it will temporary
shun the host until replication catches up. Please see the official
`upgrade notes <https://proxysql.com/documentation/main-runtime>`__
for more detail.
