SSO Improvements - Role configuration support

We have added more roles to choose for the default role in the SSO configuration settings and also introduced an optional custom key/value pair called role with possible values Admin, User & Stakeholder which will overwrite the configured default user role.

This custom key - value may not be supported by all SSO providers.
