Expose Request Body to the CEL Evaluator

[twolffpiggott]

According to the documentation and referring to the codebase, the request body is not exposed to the CEL evaluator.

In principle it should be possible as the request body is available as an attribute on the Lura proxy.Request object being handled.

It would be a very useful feature to be able to evaluate JSON request bodies using CEL as we are able to evaluate the response data.

Is this a feature that would be considered or that guidance could be provided to implement?

Or are there complications to the implementation that aren't immediately obvious to an outsider?

Thanks for your time!
