Health check capability

[peterpijpelink]

Describe the feature

Could it made possible with a sort of stoplight/traffic light idea that the supervisor shows after a restart or upgrade that all is functional working? Now it shows a three lines as supported or so. But I would love to see a message if an app or integrations fails to start or an error happend during the start of core for example.:

Use cases

After an upgrade it would be helpful to see all is working fine. This is useful for HA running remote or without active monitoring. Supervisor could be the watchdog for all apps and integrations. Often after an upgrade it takes time to figure out why something is not working, and then Z2M is not started for example.

Current workarounds

Now I go check logfiles and all the integrations to see if they all still work. That is a manual job, and since HA shows already with a red indicator that something is wrong on an integration, why not automate this into Supervisor so it is a one overview. Green all good, Yellow/Orange issue Red error.

Anything else?
