Traefik 2.2 with automatic https via let's encrypt

[fititnt]

Most guides about Traefik are outdated (using Traefik 1.x, the 1.7 still with a lot of user base) and the default configuration examples for Traefik 2.x do not provide Let's Encrypt enabled by default. Actually, Traefik 2.x have more configuration options than the 1.x series, but this broke the compatibility.

This issue is to make a combo with the traefik.toml + docker-compose.yml that deliver valid HTTPS.

The automatic https already is working. Maybe one thing missing is implement an middleware that make easier to specify on docker-compose labels that the user wants to redirect from http to https. But I have no idea on how to do it on Traefik 2.2 yet, so I will do on next run.
