[repo] resolved conflict with LZ4. Bumped version of the client to 0.9.6

[chernser]

Summary

org.lz4 Relocated → at.yawk.lz4 » lz4-java. But classes are available at the same package. So this PR fixes artifact resolution.

Another problem - we do not know if client compatible with provided LZ4 library at runtime so we need to shade that library and ship with zip.

ClickHouse Version is upgraded to 0.9.6 because later has some compatibility issue and changing too much is risky.
