Currently only a single job for a single unit can be enqueued atomically, so there is no guarantee that, e.g., starting a unit and its socket at the same time will happen in the same transaction. That forces callers to 'know' the right order in which to start new units being installed, or failures will occur. It also means some ordering constraints are ignored, in case the separate calls are done in the wrong manual order. Add a new EnqueueUnitJobMany() D-Bus method that takes a list of units to start.
