Added "removeAllHealthDataRecords" method to the UserAdminService. The deleteUser call now also deletes all HealthDataRecords for an associated user, assuming they are signed in.
removed several methods from the useradminservice interface, such as removeUserAccount, since this would essentially make it impossible to delete a users data. Added a deleteUserGlobal method, which deletes a users information from all studies he or she may be involved in.
Added suspend/resume data sharing stubs to consent service and controller.

Added "removeAllHealthDataRecords" method to the UserAdminService. This is not complete but we need to check it in to fix the service interfaces so none of the services refer to our session store.
