[Feature]: Allow API Keys to be loaded from files, not just environment variables or directly in the config.yaml

[bexelbie]

The Feature

Add a new pattern to api_key in the config file to allow for file/ to denote that a file reference follows.

Motivation, pitch

This allows keys to be stored in temporary files that exist during startup or in secured locations and not in plaintext with the config or visible in the process tables/container inspection. This also allows for the config to be committed to git without concern or stored in a non-secured location.

This is similar to the existing os.environ and oidc prefixes.

Note: This issue was edited as I had missed how the environment variables were referenced as my initial use has been with placing hte keys directly into the configuration file.
