Health check CamelBeanBuildItem should use the check id as the name

[jamesnetherton]

There's a BuildStep in the microprofile-health extension which discovers health checks and creates a CamelBeanBuildItem for each of them. At present the simple name of the health check class is used as the bean name. We should use the id assigned to the check since there are some places where this is referenced in Camel.

E.g camel.health.contextEnabled=false does not work because the ContextHealthCheck cannot be found by the expected registry lookup key.
