On macOS I use Tunnelblick to manage vpns, but on linux these tools
don't really exist, and it's also nicer to be able to open the vpn
connection via the command line rather than having to have a GUI up to
connect.
This excempts my two emacs configurations for spacemacs and doom-emacs.
THere are still credentials in plaintext and I need to solve how to
store those in git without the credentials.
