* [FEATURE] Docker simplification and configuration generation
The Authelia binary now will attempt to generate configuration based on the latest template assuming that the config location specified on startup does not exist. If a file based backend is selected and the backend cannot be found similarly it will generate a `user_database.yml` based a template.
This will allow more seamless bootstrapping of an environment no matter the deployment method.
We have also squashed the Docker volume requirement down to just `/config` thus removing the requirement for `/var/lib/authelia` this is primarily in attempts to simplify the Docker deployment.
Users with the old volume mappings have two options:
1. Change their mappings to conform to `/config`
2. Change the container entrypoint from `authelia --config /config/configuration.yml` to their old mapping
* Adjust paths relative to `/etc/authelia` and simplify to single volume for compose

* [FEATURE] File Secret Loading
* add a validator for secrets
* run the secrets validator before the main config validator
* only allow a secret to be defined in one of: config, env, file env
* remove LF if found in file
