Add multiple health sensors and device info

Introduce HealthSensorEntityDescription and a tuple of sensor
descriptions for integration status, source IP, base URL and addon
response. Instantiate one HealthDiagnosticSensor per description in
async_setup_entry. Update HealthDiagnosticSensor to accept a
description, derive unique_id from description.key and add a cached
device_info returning a SERVICE-type device. Adjust imports.
