* Add pubsub to render_queue and base_worker * Refactor: Convert ZeroconfServer to Singleton with Class Methods * New API for subjob servers to notify parent job servers of status changes * Refactor: Move all subjob related methods to distributed_job_manager.py * Rewrite for wait_for_subjobs * Fix: DistributedJobManager.find_available_servers() takes 1 positional argument but 3 were given * DistributedJobManager should now notify / be notified abotu background job changes * Fix the make_ready api. Change children keyname to be id@hostname so it can be unique * Fixes * Image sequence to movie needs to find the actual start frame * Fix: subjob_status_change did not return a valid response * Fix client renderer selection * Small fix for subjob status checking * Fix issue with divide_frames_equally * Fix issue where downloads were not occurring * Fix issue where old status was being reported * Add docstrings and code cleanup
