[feature request] upload videos as draft

[coooo77]

Because videos uploaded may contain copyrighted material, have to check and save video manually. It's possible to not save videos?

BTW, there are some problem using youtube-uploader

1. minimum required options to upload video doesn't contain channelName, but it's required in types. And dunno what exactly channelName works, uploading stuck when i specified it.
2. function upload can be specified an array of videos, but i failed and it's ok to upload single video. I solved it with reduce

[video1, video2].reduce((acc, cur) => acc.then(() => upload(credentials, [cur], { headless: false })), Promise.resolve(['']))

channelName feature was added by someone else, I did not test it. If you would like to have a new feature or fix any bugs, please send a PR
