provide .well-known endpoint for oidc

[ymajoros]

For openid-connect, the spec specifies that the endpoint should be /.well-known/openid-configuration

This conflicts with the currently default path, which seems to suit OAuth2 well though.

I suggest adding a flag to choose between OAuth2 only or OIDC.

Does setting the discoveryEndpoint currently work for you? I assume this request is only to make it easier to 'guess' the openid endpoint, right?

Yes, it works (but see other reported bugs). This is just a feature request for convenience.
