quarkus-camel - Use MainSupport as base for running Camel

[davsclaus]

We should look at using MainSupport (parts of Camel Main) some more for bootstrapping camel-quarkus.

Then its similar across standalone Camel, Camel K, and Camel Quarkus. And also Camel Main has parts that are similar to Camel Spring Boot.

This should be easier to do now that we are on Camel 3.0.0.M4. Any hints or examples @davsclaus how to do that?

As today core is responsible to act like a main but for better flexibility (i.e. for other to build on top of core) I think we need to split responsibilities like:

1. core to set-up low level things such as:
   • camel context
   • registry
   • integration with quarkus event loop Add support for quarkus provided event loop #131
2. main to set up application related things, like:
   • initialize, start/stop the camel context created by core
   • discover routes
   • discover and register life-cycle interceptors (to allow i.e. camel-k to hook into the static init build processors)
   • integration with quarkus health checks Expose health in quarkus  #141
   • integration with quarkus metrics Expose metrics in quarkus #128
   • fire CDI events
