Debug test with specific set of environment variables

[nfx]

Is your feature request related to a problem? Please describe.
This extension gives a great code lens to debug a test, though it seems not to be possible to debug test with a different set of environment variables. .vscode/launch.json doesn't seem to be picked up. This approach is very handy in troubleshooting regressions or experimenting with an existing code.

Describe the solution you'd like
Ability to debug a GoLang test with different sets of environment variables and possibly other flags.

Describe alternatives you've considered
The workaround is to launch vscode process with specific set of environment variables, but this is sub optimal.
