Support for verbose mode: log HTTP request and response

[mkuratczyk]

Is your feature request related to a problem? Please describe.

When things don't work the way I'd expect, I usually want to see what was actually sent to the server and what the response was exactly. Something similar to curl's -v option would immediately show whether the problem is with me/rabbitmqadmin-ng/rabbitmq-http-api-rs or is it RabbitMQ that handles the intended request in a surprising way.

Describe the solution you'd like

-v / --verbose flag

Describe alternatives you've considered

No response

I was thinking about adding a minimalistic version of logging for key request values.

Similarly to what we report for 404 responses now, a URL and a body.

I am not sure reqwest would make it easy to log the headers in addition.
