feat(server): role based authentication system (#2434)
- Parse toml configuration file, see https://github.com/qdm12/gluetun-wiki/blob/main/setup/advanced/control-server.md#authentication - Retro-compatible with existing AND documented routes, until after v3.41 release - Log a warning if an unprotected-by-default route is accessed unprotected - Authentication methods: none, apikey, basic - `genkey` command to generate API keys Co-authored-by: Joe Jose <[email protected]>
