Have a small TUI to work with the Launchpad queue

[Hyask]

Goal

• Using Python and launchpadlib, we need to build a small standalone TUI tool to work with the upload queue.
• The queue is here: https://launchpad.net/ubuntu/resolute/+queue?queue_state=1
• The TUI needs to list all items in the queue, and provide various actions on them:
  • Review, showing the debdiff between what's currently in the Ubuntu Archive and the new package uploaded, be it directly to Ubuntu, or a sync from Debian.
  • Accept
  • Reject, asking for a comment to provide context on the rejection.

Context

• https://launchpad.net/ubuntu-archive-tools this git repository has many examples on how to use launchpadlib. The queue script in there already provides some functionality, but is inconvenient and does many things wrong, like using regex on HTML, so don't do that.
• In the case of a sync, you can fetch some Debian context from the Debian tracker (https://tracker.debian.org/pkg/<package_name>), but the package should already be imported by Launchpad, and that's where you need to grab the .dsc file for diffing:
  • https://launchpad.net/debian/+source/<package_name> for the Debian side
  • https://launchpad.net/ubuntu/+source/<package_name> for the Ubuntu side
