Debugging nameko services with Visual Studio Code

Ok, so I ended up creating a 'debug.py' file in the directory containing my
service projects, containing:

import sys
from nameko.cli.main import main
main()

Then, in the launch.json for each of my projects, I have:

"pythonPath": "${workspaceFolder}\\env\\Scripts\\python.exe",
"program": "${workspaceFolder}\\..\\debug.py",
"args": [
    "run",
    "service",
    "--config",
    "config.yml"
],
"cwd": "${workspaceFolder}"

This seems to work fine -- environment-variable substitution when
processing config.yml works as expected.
