Support multiple test environments

When I use test explorer in Python it allows me to run tests just in one way, but I cannot believe I'm the only one who need to run tests with different pytest args or with different env variables. PyCharm for example allows to create different test runners with specific arguments and environment variables in each one.

The community seems to have been showing interest for years, I've found this old issue with the same request. #12075

I would like to know how Brett Cannon (@brettcannon) or others are running tests with vscode-python... I think they don't even use the extension, because it's impossible to use python professionally in vscode without these type of features.

It only works for students who are using just one test suite while learning.
