[midPoint] REST authentication

[Adam Davenport]

We also have a requirement to call the midPoint API on behalf of a particular user.  Not only for the delegated administration mechanisms but also for auditing.  We plan on having a home grown application that users will use that calls the midPoint API.  We require midPoint to audit that userX performed an action on userY rather than the audit record indicating "application user" performed the action.  However, storing userX's credentials to send in the API calls is not a feasible practice.  Thank you.
