OpenID Support for openSUSE Build Service

by udit for openSUSE Project

The goal is to have a instance of the Build Service where users can log in with an OpenID. The specific requirements are: * Enabling users to login and register with OpenID * OpenID UI for the Web front end * Associating an API key with user * Extending the Authentication mechanism of API to support login via API key * Evaluating/Implementing OAuth to provide access to API Login through OpenID will provide a better user experience to the Web Front end users.
