Dex - Multiple Connectors workflow Issue

[SaurabhAZip]

I am using multiple Identity Providers say

1. google and
2. github

Now openid configuration is served through following URL
https://DOMAIN_NAME/.well-known/openid-configuration

and https://DOMAIN_NAME or https://DOMAIN_NAME/auth opens up the page to choose between the 2 Idp's configured.

Since, client uses https://DOMAIN_NAME/.well-known/openid-configuration path for auth, users have to select one of the IdP's configured (client uses root path for auth as configuration is served by root path)

However, I want client to use(for this scenario) https://DOMAIN_NAME/auth/github or https://DOMAIN_NAME/auth/google directly and pre-select one of the options.

For that to work, Dex should be able to serve
https://DOMAIN_NAME/auth/{connector}/.well-known/openid-configuration so that client can directly call https://DOMAIN_NAME/auth/{connector} for auth.

It might make sense to support https://DOMAIN_NAME/auth/{connector}/.well-known/openid-configuration end-point in case of multiple connectors configured in Dex.
