most of the fields can keep private if code is reused properly

This will be supported at ClickHouse/clickhouse-java#894 0.3.3 directly by:

String connString = "jdbc:ch://server1,server2,server3/database"
    + "?load_balancing_policy=random&health_check_interval=5000&failover=2";

Closing and waiting for a version bump...
