Host OIDC configuration for non-default issuer

[Shurgentum]

What feature do you want to see added?

When a jenkins endpoint is publicly unavailable, it creates a need to host the jwks and openid-configuration files separately. Unfortunately, this approach is difficult/impossible to automate and avoid manual file uploads.

There is a more practical approach - so that with a non-default Issuer, you can configure a proxy or Load Balancer with a different domain name and filter traffic using the url path.

Proposal

Add a checkbox when creating OpenID Credentials, upon activation of which Jenkins will host files on its own, even with non-default Issuer.
