Add a health check API to camel-core so this API can be queried from Java / JMX / spring-boot etc. so users can easily get a health check. This can be used for liveness/readiness checks for their Camel apps.
The API should allow optional support for components to implement custom logic for health check. So a FTP component can connect to a FTP server and do a FTP list etc. A JDBC component does a SQL query, and so on.
