title: RabbitMQ - shovel plugin, accessing headers (properties) form Azure Service Bus
body: <p>I need to implement rabbitMQ as sort of a middleware between Azure service bus and my rails app.
  The message that is being sent uses headers which i also need to capture.</p>
  <p>So, is there a way for shovel-plugin to also include headers with the shoveled payload?
  Whenever i get the message from the shovel all the original headers are gone.</p>
  <p>Also I am using Bunny as an amqp client in the app</p>
  <p>Thanks!</p>
  <p>EDIT:
  Found this PR thanks to RabbitMQ slack:
  <a href="https://github.com/rabbitmq/rabbitmq-server/issues/2745" rel="nofollow noreferrer">https://github.com/rabbitmq/rabbitmq-server/issues/2745</a></p>
  <p>It seems that they are aware of the issue</p>
  <p>I just created a Python middleware that handles appending headers to the payload and passes the data to RabbitMQ queue later on since it's literally 30 lines of code</p>
