I realize this is less than ideal but I think we can accept it for the short time until the required releases are stable

This reverts commit 27ec5b77.

- glances: Helpful tool to see everything going on in the server in real time
- tokei: Like cloc but doesn't suck
- bat: A really neat auto-paging cat with syntax highlighting that use pretty often
- hexyl: Look at binary stuff

These are required for a working build server.

Leaving "dns" out of "hosts" breaks DNS lookups when resolved is
stopped.

This is because otherwise we'll fail to install on any system not explicitly running Python 3.7 (like some Debian we provision Arch on).
We don't strictly need Python 3.7 and most Python 3 versions will in fact work with Ansible.

We've changed ansible to use python3 now and Python 2 will be deprecated
next year.
