[feature] Add option to use localhost as redirect host for oauth2

PR Description:

Some oauth2 implementations (eg the MS Sharepoint implementation) do not support http://127.0.0.1 redirects. They allow only https://127.0.0.1 OR http://localhost redirects.

Since https is not simple to support, instead expose an option to allow localhost for redirects.
