title: jhipster- how to add a new role
body: <p>I am trying to add a new role (ROLE_REPORTS) on a project generated using JHipster. I can see the tables that need to be updated (role, authority and role_authority mapping), but I am not sure how to go about the Java part of it.</p>
  
  <p>There a few bits and pieces I can figure out, but I am concerned that my customisation may break some design philosophies (like the Swagger API, Spring Security, etc.,)</p>
  
  <p>Has anyone already attempted it and if so any help in the right direction will be highly appreciated.</p>
