Add an option to also get the body in the HTTP protocol.

It's commented for now because it's too huge:

An option in the HTTP modules which use our "protocol" is also needed (we can add a common options cfg file for HTTP like the one we have for SIP - https://github.com/jesusprubio/bluebox-ng/blob/03e574484205b85a1b1b269b9be7cfa655ae89ae/bin/cfg/commonOpts/sip.json):
