Description

Message headers (properties, in Service Bus parlance) are not currently propagated to/from Camel Message headers aside from within the CamelAzureServiceBusApplicationProperties header.

Crucially, the lack of header propagation means that trace context propagation does not work when using Azure Service Bus.

I have implemented and tested the necessary header propagation and created a PR. Please let me know if I need to target a later version, or if we need to make the new behaviour switchable in order to make it suitable for a patch release.
