/** Tries to parse ClickHouse connection string.
 * if @connection_string starts with 'clickhouse:' then connection string will be parsed
 * and converted into a set of arguments for the client.
 * Connection string format is similar to URI "clickhouse:[//[user[:password]@][hosts_and_ports]][/dbname][?query_parameters]"
 * with the difference that hosts_and_ports can contain multiple hosts separated by ','.
 * example: clickhouse://user@host1:port1,host2:port2
 * @return Returns false if no connection string was specified. If a connection string was specified, returns true if it is valid, and throws an exception if it is invalid.
 * @exception Throws DB::Exception if URI has valid scheme (clickhouse:), but invalid internals.
