Support for not using discovery, and pass the required fields explicitly

[Ulrar]

Hi,
I have a bit of a niche use case I suppose but I'm running home assistant and pocketid on the same kubernetes cluster.
The issue is home assistant, as it's running in network host mode, cannot reach pocketid's external address (or rather, it's IP), and that's not trivial to fix.

Since the discovery URL is returning a bunch of fields containing that unresolvable domain, could it be possible to instead specify each of these in the config file instead ? That way I could just define them using the in cluster URL instead, which works.

auth_oidc:
  client_id: "60b0433a-d3f4-4401-bfc5-fa31227ce082"
  discovery_url: ""
  token_url: "http://pocketid.pocketid.svc.cluster.local:1411/api/oidc/token"
  user_url: "..."

Thanks
