Is it possible to pass messages to message queue (like RabbitMQ)?

[RredCat]

Expected Behavior / New Feature

I am expecting to have a configuration that allows me to pass messages to the message queue.
It could be something like:

{
  "UpstreamHttpMethod": [ "GET", "POST", "PUT", "DELETE", "OPTIONS" ],
  "UpstreamPathTemplate": "/gateway/{catchAll}",
  "DownstreamPathTemplate": "/{catchAll}",
  "DownstreamScheme": "RabbitMQ",
  "DownstreamHostAndPorts": [
    { "mqOptions":"some options" }
  ]
}

Actual Behavior / Motivation for New Feature

At the current moment, it is possible to use "http", "https" and "ws" as a value for "DownstreamScheme".

Is it possible to implement such behavior?
