Create YouTube playlist

Creates an empty playlist on the connected YouTube channel. Requires a title; privacy defaults to private. Returns the same playlist shape as the list endpoint. Pass the returned playlist.id as platformSpecificData.playlistId when publishing a video. Does not change the account's default playlist. Requires the youtube or youtube.force-ssl OAuth scope. Costs 50 YouTube quota units. This operation is not idempotent and is not automatically retried: repeating a request can create another playlist, including after a timeout. List playlists before retrying an ambiguous failure. Official series settings are not exposed by YouTube's public API and must be enabled manually in YouTube's desktop playlist settings.
