Feature Request : send back error details

[LasneF]

When setting WireTap as a validation proxy , it would be nice to return as well the error details to the client and not only the 502

could be returning HTTP RFC problem format or whaterver

meanning instead of empty payload returning something like to have better understanding as well from client point of view.

it should include response violation as well as type and how to fix

(i know all those are in the UI but having them as well in the return would help the debugging lifecycle.

This is a good idea.
