Add Dockerfile for Stats

[pan93412]

This PR adds the Dockerfile for Stats that simplifies the deployment. The layer caching has been optimized.

Note that this is in WIP: I am still working on the server listening issues (it did not respond to any requests)

@pan93412 here's what it took for me to deploy it on fly.io

Main changes here are using a standard 8080 which happens to be what Fly wants.

Not sure why my Stats can't work with this dockerfile. @UdaraJay could you help me take a look with this?

Hi @pan93412 , I was running into the same issue when trying to run the app in the official rust image. I was able to fix it by rebinding the server to 0.0.0.0 instead of 127.0.0.1 here

Good investigation! Let me PR a HOST change later.
