* Add limit parameter to service call methods
* Break out prep part of async_call_from_config for use elsewhere
* Minor cleanup
* Fix improper use of asyncio.wait
* Fix state update
Call change listener immediately if its a callback
* Fix exception handling and logging
* Merge Script helper if_running/run_mode parameters into script_mode
- Remove background/blocking _ScriptRun subclasses which are no longer needed.
* Add queued script mode
* Disable timeout when making fully blocking script call
* Don't call change listener when restarting script
This makes restart mode behavior consistent with parallel & queue modes.
* Changes per review
- Call all script services (except script.turn_off) with no time limit.
- Fix handling of lock in _QueuedScriptRun and add comments to make it
clearer how this code works.
* Changes per review 2
- Move cancel shielding "up" from _ScriptRun.async_run to Script.async_run
(and apply to new style scripts only.) This makes sure Script class also
properly handles cancellation which it wasn't doing before.
- In _ScriptRun._async_call_service_step, instead of using script.turn_off
service, just cancel service call and let it handle the cancellation
accordingly.
* Fix bugs
- Add missing call to change listener in Script.async_run
in cancelled path.
- Cancel service task if ServiceRegistry.async_call cancelled.
* Revert last changes to ServiceRegistry.async_call
* Minor Script helper fixes & test improvements
- Don't log asyncio.CancelledError exceptions.
- Make change_listener a public attribute.
- Test overhaul
- Parametrize tests.
- Use common test functions.
- Mock timeout so tests don't need to wait for real time to elapse.
- Add common function for waiting for script action step.
