The two main entities in Tubely are videos and users. A user can have many videos, and a video belongs to a single user.

"Videos" have 3 things to worry about:
Tubely allows users to create a "new draft" - which creates a new video record in the database containing metadata only. Thumbnails and video files are uploaded separately after the draft is created.
You should now see the video in the UI with options to upload a thumbnail and video file. Don't upload the files yet.
Run and submit the CLI tests.
