[Enhancement] Add docker compose deployment examples

[ossScharom]

Proposed deployments

Add a Folder that contains multiple different deployment examples for the atcommons/mlflow-server image. Deployment examples would be described by docker compose YAMLs. A system architecture can be found here. Each example will be heavily documented by the folder's README.

Insecure

• PostgresSQL RDBMS used for parameter tracking
• Minio used as an artifact store

With Proxy

• Extends insecure deployment
• Traefik used as a reverse proxy to encrypt traffic to the remote host

Proposed directory layout

The following structure is inspired by nextcloud/docker

docker-mlflow-server/
├─ .deployment_examples/
│  ├─ insecure/
│  │  ├─ postgres_minio/
│  │  │  ├─ docker-compose.yaml
│  ├─ with_proxy/
│  │  ├─ postgres_minio_traefik/
│  │  │  ├─ docker-compose.yaml
│  ├─ README.md

Stretch Goal

Make examples easy to explore by using play with docker in the documentation.
