Description

We can look at making writing custom HealthCheck be discoverable from classpath, so they can be automatic installed.

You can then build checks for Camel components (check ala spring boot actuators) that can be registered in health check registry.

And then if you run on spring boot, they can become adapted to spring boot actuators.
And for camel-main and camel-quarkus then we can look at using microprofile-health.

This need some more thought at first. Also this should be configurable to turn on|off, and maybe a way to configure each health checks. And have some tool that can generate documentation about the checks and their options. And then we need reflection free configuration (via configurer classes) and so on.
