Support Message-based operations (e.g. $process-message operation)

Discussed in #2601

We're working with FHIR messaging. For this we opted to use the $process-message operation. This line in the specifications is giving me headaches:

This operation does not use the parameters resource; the parameters "async" and "response-url" always go in the URL, if they are used, and the "content" parameter is always the body of the HTTP message.

I don't think it is possible to do this with the FhirClient. All the operation-based functions take a Parameter object and post it to the server.

Is this something that is missing on the SDK?

Can I say duplicate of #2605 😉
