This allows use to use STDOUT directly without having to call open again, also this makes the export API endpoint much more performant since it no longer needs to copy to a temp file. I noticed that there was no export API test so I added one. And lastly opening /dev/stdout will not work on windows. Fixes #16870 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
