Support for load balance URLs

We currently use the jdbc:mysql:loadbalance feature provided by MySQL Connector/J to connect to a collection of MariaDB replicas. We would like to be able to do the same with the MariaDB JDBC driver, so that we can switch between the two drivers without introducing a new load balancing service such as HAProxy.
