Debian has enabled `EXTERNALLY-MANAGED` from PEP 668 which breaks `pip
install --user`. I think this is a terrible decision, understandable to
want to avoid modifications in `/usr/lib/python*/site-packages` but to
have that stop be installing packages in my home directory is a big
mistake in terms of usability. In any case this patch moves the
configuration of `pip.conf` to occur before any other roles are
processed, seting the override flag, even though I'm never actually
touching the real site packages.
The `autodesk-fusion360` and `prusiaslicer` roles are added to the
`Windows.yaml` playbook but disabled by default behind the
`install_cad_apps` flag. To enable them create a `~/.config/local.yaml`
file with the following:
```yaml
- import_playbook: local/Windows.yaml
vars:
install_cad_apps: true
```
Additionally:
* Stop using Chocolatey packages for 1password as they are not up to
date, instead download and install directly.
* Switch to apt repository on Debian.
* Add zsh completions for macOS and Dabian.
* Add powershell completions for Windows.
