Start Tox command from within the tox file (Test UI)

[starlord-daniel]

Additions

• added samples with a simple tox file and Python tests
• adapted gitignore
• added vscode launch settings (to use sample files)
• upgraded to vscode 1.59.0 (requirement for Test UI)
• added logic for parsing tox to get commands to run through tests
• added logic to call existing runTox for the chosen tests
• reuse of terminal

How to test

• meet the prerequisites described in the REAMDE.md
• press F5 in VS Code to run the Run Extension launch command
• in the test instance of VS Code, open the tox file
• after loading, the tox commands can be executed (from file directly or the test explorer)
• safe the tox file to trigger a re-parsing of the environments

Implements #11

FYI, I'll mostly be away until after Easter (at PyConDE and then a digital arts event) - thus, I'll probably only get to reviewing this in 2 weeks or so. Meanwhile, thanks for the contribution and your patience!

Thank you for the heads-up. I merged the changes from #9, so that we don't get conflicts, when it is merged first. Please contact me or @pkirch anytime, if you want to discuss the approaches a bit further than the discussion board.

@starlord-daniel, LGTM!

Only one remark: imho, it would look simpler and cleaner if the new functionality were in its own class.

Thanks! Merged with a couple of cleanups I noticed when trying to understand the code (or more accurately, trying to understand the VS Code Testing API 😅):

• 9826166 Cleanups in parseTestsInFileContents
• cdc0043 Use TestItemCollection.replace in parseTestsInDocument
• e92a7c1 Remove unneeded assignment
• f1b8ace parseTestsInDocument: Use path.basename
• 3875b2f Simplify open/save registration

I also opened a couple of follow-up issues I'd appreciate your input on:

• Remove enabledApiProposals: ["testCoverage"]? #23
• Tests from tox.ini are not picked up until it's reopened #24
• Support pyproject.toml and setup.cfg for features operating on tox.ini #25
