Add support for auth with OIDC (Authelia)

[PylotLight]

Is your feature request related to a problem? Please describe.
In order to access self-hosted AI behind a personal server hosted externally, instead of having to patch holes in fw rule lists, it would be better to consume OIDC auth via cli to allow secure external connections to privately hosted endpoints.

Describe the solution you'd like

• Set ___domain endpoint for AI in mods.yml config
• When requests are made, if unauthed and hit auth redirect request and store auth token to consume for future calls

Describe alternatives you've considered
E.g Consume/integrate this tool: https://github.com/authelia/ac

Additional context
You can achieve auth via OpenID Connect 1.0, just have to setup a client which accepts a localhost redirect, then listen for the response on a short-lived http server. An unpolished but working example exists here: https://github.com/authelia/ac
