See Request body as well as headers

Coming from #174

I Would love to be able to see the request body as well as the response body and headers. So That I Can document and extract fixtures for applications, which come from real production or sandbox API's, allowing me to compare changes in API specification, or documentation.

Challenges to this are I guess needing to place this at the end of module.exports.requestHooks so that plugins that modify the request are also taken into account.

A Bit of context, the reason I would like this is that a provider we use at work is using https://github.com/TrueLayer/insomnia-plugin-jws/blob/master/main.js to sign requests. I Would like to be able to see the traffic. For now I can work around this (I believe) by using ngrok to forward requests to the upstream service.
