Description

Working to create a camel-kamelet component here: https://github.com/apache/camel-k-runtime/issues/375 and there is an issue when the routes templates are materialized:

Assuming I have a route template defines as:

routeTemplate("setBody")
    .templateParameter("bodyValue")
    .from("direct:{{routeId}}")
    .setBody().constant("{{bodyValue}}");

And a route like:

from("direct:template")
    .to("kamelet:setBody/test?bodyValue=bv")
    .to("log:template");

Then the kamelet component would try to create a route named test out of the setBody template and:

1. if the route is create upon KameletComponent::createEndpoint, then the camel context would fails to materialize the template as there is a concurrent exception because a new route definition is added while the context is iterating over them
2. if the route is created upon KameletEndpoint::onStart, then the route is not added to the camel context
