Save http trace to a file instead of displaying it onto the console. the environment variable MINIO_HTTP_TRACE will be a filepath instead of a boolean. This to handle the scenario where both json and http tracing are turned on. In that case, both http trace and json output are displayed on the screen making the json not parsable. Loging this trace onto a file helps us avoid that scenario. Fixes #5263
