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

Start by reproducing the Maven import with com.clickhouse:clickhouse-jdbc:0.7.2 using the http classifier, then inspect the resolved dependencies for clickhouse-data and jdbc-v2. Focus on the duplicate classes com.clickhouse.data.stream.Lz4InputStream and Lz4OutputStream. Done means the dependency no longer produces duplicate-class warnings.
