Simplify ClickHouse startup - use default configuration

Remove custom --path option which causes 'Unknown option specified' error.
ClickHouse pre-built binary expects to run with default configuration.

Changes:
- Run simply: ./clickhouse server
- Let ClickHouse use its default data directory
- Added 5s initial sleep to allow server to initialize
- Removed invalid --path, --http_port, --tcp_port options

ClickHouse listens on default ports (9000 for TCP, 8123 for HTTP) which
matches what our tests expect.
