Docker Secret Support

[beny2000]

Hi, love the project. It's the most straightforward approach to monitoring I've come across. I was wondering if there is (or will be) Docker secret support for environment variables. I'd like to be able to specify the agent key in a Docker secret and pass the file path as the environment variable, as is common with other services.

For example, being able to do something like this would be great

beszel-agent:
  image: henrygd/beszel-agent
  network_mode: host
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock:ro
  environment:
    PORT: 45879
    KEY_FILE: /run/secrets/beszel_agent_key
  secrets:
     - beszel_agent_key

Thanks

Added support for this in #412
