Add label property to debug config, change pkg name to lowercase (#1746)
Add label property to debug config, change pkg name to lowercase (#1746)

I don't think we should merge this to v1.x.  I want to take the
opportunity with the preview to make sure package.json name prop change
to "powershell" doesn't cause any problems.

This addresses issue caused w/LiveShare ext loaded and you try to debug.
While this issue has been fixed by a mod to the next verson of VSCode,
we should have our debugger configured properly.
See https://github.com/Microsoft/vscode/issues/61649

Also, made debug snippet prop order consistent: name, type, request.
