Add Device Health Check and Device Settings

[jake9190]

I believe this would be useful for the community. This PR adds a few features:

1. Adds Health Check capability (healthStatus attribute), checked via refresh every 30 minutes
2. Adds parent methods to support changing device settings via PATCH (this should work for most settings)
3. Add motion snooze (in minutes) for a specific device
4. Adds command to enable/disable motion triggered lights
5. Adds SetLevel to Light w/ Siren to enable changing brightness of the floodlight

I didn't have other device types to test with, so these changes were only made to Virtual Camera, Virtual Camera w/ Siren, Virtual Light, Virtual Light w/ Siren

Happy to split these up if its preferred.
