Description

When:

• using Camel with CDI
• having routes defined in multiple beans 
• one bean defines the route template
• another bean attempts to create a route from that template

I would expect that the route templates are configured before any routes that build from them.

What happens is non-deterministic based on the order the RoutesBuilder instances are provided by the CDI runtime. In a good case, the template bean is processed first and all is as-expected. However, when the template bean is provided after any bean that attempts to build from it we get the error:

Caused by: java.lang.IllegalArgumentException: Cannot find RouteTemplate with id ListProcess
{{ at org.apache.camel.quarkus.core.BaseModel.addRouteFromTemplate(BaseModel.java:167)}}
{{ at org.apache.camel.quarkus.core.FastCamelContext.addRouteFromTemplate(FastCamelContext.java:188)}}
{{ at org.apache.camel.builder.TemplatedRouteBuilder.add(TemplatedRouteBuilder.java:104)}}

Attempted a workaround by annotating the template bean with @Priority(1), however this had no effect.
