* Fire EVENT_HOMEASSISTANT_START automations off right away while starting * Actually have core state be set to 'starting' during boot * Fix correct start implementation * Test and deprecate event automation platform on start * Fix doc strings * Remove shutting down exception * More strict when to mark an instance as finished * Add automation platform to listen for start/shutdown * When we stop we should wait till it's all done * Fix testing * Fix async bugs in tests * Only set UVLOOP when hass starts from CLI * This hangs normal asyncio event loop * Clean up Z-Wave node entity test
