adding body to logging

at the moment there is no possibility to log the payload of request and response using the logging policy https://access.redhat.com/documentation/en-us/red_hat_3scale_api_management/2.9/html/administering_the_api_gateway/apicast_policies#logging_policy

it is clear that logging it will have a performance impact because nginx will need to open the payload (https://stackoverflow.com/a/17765232/9326792) but could we add an optional setting in apicast to change this default behavior to enable logging payloads?
