Allow viewing the raw request and response for debugging when using the SDK

Feature Request

Is your feature request related to a problem? Please describe

When using the SDK, sometimes I want to debug the call. Often this happens when a call fails and I want to verify what's going over the wire and what's coming back to determine if it's the Graph API or the SDK that's failing.

Describe the solution you'd like

I'd like to be able to put the Graph client, or a call in debug mode, where I get to see the request and response (URL + payload + headers) that go over the wire.

Describe alternatives you've considered

In a browser I can get this information from the network tab, but in Node apps, this would require a proxy which is inconvenient.

Additional context

Perhaps we could use implementing this feature using middleware, where we offer additional middleware that's logging requests and responses to console or better yet, offers a callback that allows me to decide how I want to deal with the information.

Very relevant as I was discussing the same with @nikithauc last week. Right now you can put the client in debugging mode and it will console.log the URL. I would prefer to have a handler where I could play with the generated URL (log it, Unit Test it, etc.).

Last bullet of my LONG feedback issue :)

#989

Also, not only the URL but the whole request with headers and body if any, and then the response as well.

I am getting a very opaque error like this:

Error invalid json response body at https://graph.microsoft.com/v1.0/me/messages?$top=50&$skip=44867&$orderBy=lastModifiedDateTime+DESC reason: Unexpected end of JSON input 
    node_modules/node-fetch/lib/index.js:273:32 
    node:internal/process/task_queues:96:5 processTicksAndRejections

It would be very useful to be able to debug log the raw response
