Allow custom OIDC provider

[winston0410]

From the source here, I can see there are 3 OIDC providers supported by default

backend/admin-ui/src/pages/settings/auth-providers/[id].tsx

Line 139 in 16aed0e

userInfoUrl: "https://graph.microsoft.com/oidc/userinfo",

But I wonder if I can define my own OIDC provider, and disable these default providers? I guess to achieve that, we might have to create a table in Postgres to record that. Alternatively env variable should do the job as well.

Hi @winston0410,
you can use your own OIDC provider. The provided templates are just meant as a quick start.
