Kafka dev mode config propagation of kafka.bootstrap.servers to camel.component.kafka.brokers does not work

[jamesnetherton]

We have dev mode build time logic where we get the value of the container kafka.bootstrap.servers property and map it to a runtime config property for camel.component.kafka.brokers, so that Camel can use devservices without any additional config.

Something has changed on the Quarkus side because it's now not possible to get the config at build time. It's only present at run time. So we'll probably have to adjust things to restore the previous behavior.
