- Nicer symlink creation for Bash completion.
- Symlinks for Helm2 binaries so they'll be in the PATH.

Now I don't need to have any handling of completions in rcfiles,
everything is in the image, ready to go (in case anybody but me will
ever use this stuff, they will have a nice experience).

Because that's what I need.

- First of all, Hashicorp now has a proper Debian repository with a lot
  of their tools avaiable. Use that instead.
- Replace some of the other packages manaully.
- Remove the buildpack package completely (I never used it, I wanted to
  give it a try sometime).

- tracepath.
- ip, ss and the rest of the iproute2 package.

For security reasons.

Homebrew doesn't have a binary package. Get the jar from Maven and a
small script to run it using the JVM.

The Debian fails to install on Debian Bullseye (and probably some of the
newer Ubuntu releases as well) and the issue in GitHub has been open
since January 2021. Instead build just the CLI part. Should be a little
cleaner too (no Cron jobs).

Moved over from the vendored Makefile from rcfiles.

- Add Homebrew and install a bunch of utilities with it.
- Remove the binaries Makefile (replaced by Homebrew).
- Add Bash completion to the image (instead of rcfiles). Makes the image
  more complete and self-standing.
- Add the RabbitMQ admin script from rcfiles, same as before.

I don't really like this. In fact I don't like Keybase. The CLI adds
some Cron jobs. I tried the Snap package and it stays running in the
background when close the GUI (didn't see an exit option). I may go back
to the snap and revert this if I would need the GUI.

Needed for Docker Compose over SSH. Should have been installed but
isn't.

Because there are now scheduled CI runs.

Let pip sort it out.

- Remove python3-wheel Debian package, I'm installing it from PyPI
anyway.
- Install the Debian package for pyyaml since building it seems to fail.

Maybe that will solve it.

It's unmaitained and can be easily replaced.
