camel-health - Add API for readiness/liveness

It would be good if we can add some API to camel-health in camel-api that the health check is specialized for either readiness or liveness (default both).

For example context and routes health check is for readiness.
Then there can be component specific health check for liveness (database connection is valid, and so on).

Then we can allow to perform checks based on filtering (all by default, but you can say only readiness, or only liveness etc.). There is some logic for that in the microprofile-health-check.
