Include network req/resp configuration in the rrweb payload + implement BODY_SKIPPED warning

IDK if this is already done, following up from https://www.figma.com/file/VJffxPWvRaaRJ1gywzuUre/Specs%3A-Connecting-Backend-Errors?node-id=422-25592&t=smw3XXC7lQrK2N77-0

So the request/response _meta fields will contain URL_SKIPPED warning if the network was not captured due to the URL not matching!
