LXC automation experiments

Remove old cloud-init dir

Big cloudinit-py update

This includes months of changes from the internal repo.

Remove BORG_EXTRA_ARGS from backup vars example

borg_backup update

- Remove "exit 10" that's been leftover from testing for
  who-knows-how-long! Good news is that now I know I can keep daily
  backups for almost a year without running out of space. :)
- Double number of daily and weekly backups.
- Remove BORG_EXTRA_VARS, which was always a special case. I added it
  because I didn't know about BORG_REMOTE_PATH and have never used it
  for any other purpose.

First attempt at LXC packer config

I have no idea what I'm doing here.

Fix mirroring

Yes, I failed to make the *single* repo-specific modification necessary to .build.yml
file, ha.

As ugly as it is, a `cd *` would really do the trick. But that feels
very fragile.

Mirror to github

License cleanup

IP address is automatic if omitted

This saves us a trip to icanhazip

Utility to automatically set timezone

Now that I'm not using GNOME, with all its built-in tools, this is
useful for when I travel.
