* Bootstrap / Entiy setup async * Cleanup add_job stuff / return task/future object * Address paulus comments / part 1 * fix install pip * Cleanup bootstrap / move config stuff to config.py * Make demo async * Further bootstrap improvement * Address Martin's comments * Fix initial tests * Fix final tests * Fix bug with prepare loader * Remove no longer needed things * Log error when invalid config * More cleanup * Cleanups platform events & fix lint * Use a non blocking add_entities callback for platform * Fix Autoamtion is setup befor entity is ready * Better automation fix * Address paulus comments * Typo * fix lint * rename functions * fix tests * fix test * change exceptions * fix spell
