rewrite from scratch (#8)

Signed-off-by: Akihiro Suda <[email protected]>

add example/zookeeper (1h -> 10min on 5 nodes) (#5)

standalone (without namazu swarm): about 1 hours
Namazu Swarm, Kubernetes, 5 nodes: about 10 minutes

Each of the node has 4 CPUs, 15 GB RAM

4 of 165 jobs failed. I believe we can improve 2 times faster.
