Spring Security Automatically apply .oauth2Login()

Summary

The default configuration should try to automatically apply oauth2Login under some circumstance. Perhaps it is just if spring-security-oauth2-client is on the classpath, perhaps it is if a Bean of type ClientRegistrationRepository is available.

@rwinch This issue is quite old now and at this point I don't think this enhancement is needed. I'm going to close this but if you feel we should still address it then we can revisit it.
