This is in preparation for tests based on supporting features amongst
other tweaks:
- Consolidates the filtering logic that was split across `filter_model`
and `filter_fixture`
- Allows filtering `dev` fixture by `component`
- Consolidates fixtures missing method warnings into one warning
- Does not raise exceptions from `FakeSmartTransport` for missing
methods (required for KS240)
Adds auto-off implementation. The feature stays enabled after the timer runs out, and it will start the countdown if the device is turned on again without explicitly disabling it.
New features:
* Switch to select if enabled: `Auto off enabled (auto_off_enabled): False`
* Setting to change the delay: `Auto off minutes (auto_off_minutes): 222`
* If timer is active, datetime object when the device gets turned off: `Auto off at (auto_off_at): None`
* Separate fake protocols for iot and smart
* Move control_child impl into its own method
* Organize schemas into correct places
* Add test_childdevice
* Add missing return for _handle_control_child
