HyperCloud: "admin" and "serveradmin" users can be deleted

An Improper Privilege Management vulnerability exists in HyperCloud that will impact the ability for a user to authenticate against the management plane. An authenticated admin-level user may be able to delete the "admin" or "serveradmin" users, which prevents authentication from subsequently succeeding. This issue affects HyperCloud versions 1.0 to any release before 2.1.
