Don't print "readable" stream info on Node

[damianobarbati]

A POST request with a FormData object having a file binary in it results in the following:

curl -X POST -H "Content-Type:application/x-www-form-urlencoded" -H "content-type:multipart/form-data; boundary=--------------------------465935617733580427703067" --data '{"_overheadLength":412,"_valueLength":10,"_valuesToMeasure":[{"_readableState":{"objectMode":false,"highWaterMark":65536,"buffer":{"head":null,"tail":null,"length":0},"length":0,"pipes":null,"pipesCount":0,"flowing":false,"ended":false,"endEmitted":false,"reading":false,"sync":true,"needReadable":false,"emittedReadable":false,"readableListening":false,"resumeScheduled":false,"paused":true,"emitClose":false,"autoDestroy":false,"destroyed":false,"defaultEncoding":"utf8","awaitDrain":0,"readingMore":false,"decoder":null,"encoding":null},"readable":true,"_events":{"error":[null,null]},"_eventsCount":3,"path":"/tmp/1555512197006-en-GB-2-hello-world.txt","fd":null,"flags":"r","mode":438,"end":null,"autoClose":true,"bytesRead":0,"closed":false}],"writable":false,"readable":true,"dataSize":0,"maxDataSize":2097152,"pauseStreams":true,"_released":false,"_streams":["----------------------------465935617733580427703067\r\nContent-Disposition: form-data; name="sourceLocale"\r\n\r\n","it-IT",null,"----------------------------465935617733580427703067\r\nContent-Disposition: form-data; name="targetLocale"\r\n\r\n","en-GB",null,"----------------------------465935617733580427703067\r\nContent-Disposition: form-data; name="documentContent"; filename="1555512197006-en-GB-2-hello-world.txt"\r\nContent-Type: text/plain\r\n\r\n",{"source":{"_readableState":{"objectMode":false,"highWaterMark":65536,"buffer":{"head":null,"tail":null,"length":0},"length":0,"pipes":null,"pipesCount":0,"flowing":false,"ended":false,"endEmitted":false,"reading":false,"sync":true,"needReadable":false,"emittedReadable":false,"readableListening":false,"resumeScheduled":false,"paused":true,"emitClose":false,"autoDestroy":false,"destroyed":false,"defaultEncoding":"utf8","awaitDrain":0,"readingMore":false,"decoder":null,"encoding":null},"readable":true,"_events":{"error":[null,null]},"_eventsCount":3,"path":"/tmp/1555512197006-en-GB-2-hello-world.txt","fd":null,"flags":"r","mode":438,"end":null,"autoClose":true,"bytesRead":0,"closed":false},"dataSize":0,"maxDataSize":null,"pauseStream":true,"_maxDataSizeExceeded":false,"_released":false,"_bufferedEvents":[{"0":"pause"}],"_events":{},"_eventsCount":1},null],"_currentStream":null,"_boundary":"--------------------------465935617733580427703067"}' http://localhost:8080/dummyservice

Would you consider using the -F 'param=value' flag and the @ notation for file uploads?
Example:

curl -s 'https://localhost:8080' -F 'param=key' -F 'file=@"files/hello world.txt"'
