Because:
* It can be useful to debug multiple services at once.
This commit:
* Adds a pm2 config that starts 4 of the servers using start-dev-debug
with unique inspect ports so that they can be debugged all at the
same time.
* Updates the package.json files for these services so they don't choose
the same port.
* Documents the ports used for debugging.
* Add's an attach debug for VS Code that lets one choose which process
to debug.
