Summary

Added simple test.
I have run it from an external app that imports the dependency.

<dependency>
      <groupId>com.clickhouse</groupId>
      <artifactId>clickhouse-jdbc</artifactId>
      <version>0.8.2</version>
      <classifier>shaded-all</classifier>
</dependency>

It works

Adding as a fallback to load from a class's class loader (for example, in DbVisualizer)

Closes #2245
