Cloning an image can be slow, if the image is not on a btrfs subvolume, hence let's make sure we do this asynchronously in a child process, so that machined isn't blocked as long as we process the client request. This adds a new, generic "Operation" object to machined, that is used to track these kind of background processes. This is inspired by the MachineOperation object that already exists to make copy operations asynchronous. A later patch will rework the MachineOperation logic to use the generic Operation instead.
