 #### Get update status
-Retrieves the current state of each "package" available for update.  Typically
-this will consist of information regarding `moonraker`, `klipper`, `system`
-packages, along with configured clients.  If moonraker has not yet received
-information from Klipper then its status will be omitted.  One may request that
-the update info be refreshed by setting the `refresh` argument to `true`.  Note
-that the `refresh` argument is ignored if an update is in progress or if a print
