Detect and create tasks for task runners

[brettcannon]

The ask

Hi, I just found out about vscode tasks, and I thought it'd be cool if there were support for auto-detecting tasks for some of the Makefile-like frameworks in the python ecosystem.

Example Frameworks

• pyinvoke
• tox
• nox

upstream concern

I'm not sure which of those frameworks support exporting "task" information in a structured format, but I'm sure it wouldn't be too hard to implement upstream.

in closing

Thanks y'all! Apologies if there's already an issue tracking this
