Improve docker compose to include monitoring and NATS by default

[gabrielpetry]

Changes:

• Add nats support by default
• Include Prometheus monitoring by default
• Improve how to set up using profiles and files separated.
• Include a wrap script for setting up the environment
• Modify variable substitution to play better with podman.

Separated files

Due to the numerous components now in place, separating them into multiple files allows for better separation of concerns, as podman-compose is not fully compatible with docker-compose, we have to use multiple calls to --file instead of using the top-level include.

rocketchat.sh

This script downloads the latest compose files from GitHub and ensures the consistency of the .env file, avoiding problems in variables, and ensures consistency in the deploy.
