Duplicate Classes while importing clickhouse-jdbc

## Description
While importing in maven project only this dependency

com.clickhouse
clickhouse-jdbc
0.7.2
http

I receive the following warnings:

[WARNING] Found duplicate and different classes in [com.clickhouse:clickhouse-data:0.7.2, com.clickhouse:clickhouse-jdbc:0.7.2:jar:http, com.clickhouse:jdbc-v2:0.7.2]:
[WARNING] com.clickhouse.data.stream.Lz4InputStream
[WARNING] com.clickhouse.data.stream.Lz4OutputStream

### Expected Behaviour
No duplicated classes must be found

首先使用 http classifier 重现 com.clickhouse:clickhouse-jdbc:0.7.2 的 Maven 导入，然后检查 clickhouse-data 和 jdbc-v2 的已解析依赖。重点关注重复的类 com.clickhouse.data.stream.Lz4InputStream 和 Lz4OutputStream。当该依赖不再产生重复类警告时，即表示完成。
