Maybe an earlier callback can be added to CamelContextConfiguration?
But instead of using that callback you can use some spring annotation
that creates this component and name it wmq. Then Camel lookup in the
spring bean registry for "wmq" when it wants to use the component with
that name, and uses your bean.
