Simple load balancer in Rust

Part of coding challenges by John Crickett

1. Round-robin algorithm
2. api servers in node (10 of them)

Docker

1. build the images on ./Dockerfile and ./js-server/Dockerfile
2. run docker compose up

TODO

• use 'time elapsed' to check bottleneck
• third implementation: use Arc on reqwest http client in order to remove the currently bottleneck (in theory).
• setup everything in docker
• improve docker setup (one server by container)
• push to github
