ClickHouse/tests/clickhouse-test
Azat Khuzhin e2e62ce273 clickhouse-test: replace clickhouse-driver with http interface (via http.client)
Cons of clickhouse-driver:
- it is one more extra dependency
- it does not have correct timeouts (only for socket operations, and
  this is not the same, so we need to set timeout by ourself)
- it is one more thing which can break (@alesapin)
