python 3.8: migrate independent formulae

[bayandin]

• Have you followed the guidelines for contributing?
• Have you checked that there aren't other open pull requests for the same formula update/change?
• Have you built your formula locally with brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
• Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
• Does your build pass brew audit --strict <formula> (after doing brew install <formula>)?

---

This PR migrates to [email protected] independent formulae which:

• depends only on python
• doesn't have any depending formulae
• uses virtualenv_install_with_resources for installation

Ref: #47274

brew-test-bot.mojave.test bumpversion
brew-test-bot.mojave.test peru
brew-test-bot.mojave.test pyinstaller
brew-test-bot.mojave.install --build-bottle snakemake
brew-test-bot.mojave.test stormpath-cli
brew-test-bot.mojave.install ./tox--3.14.1_1.mojave.bottle.tar.gz

• bumpversion — can't reproduce locally, let's try again
• peru — looks like it calls python3 interpreter directly; dropped from the PR for now
• pyinstaller — added patch
• snakemake — doesn't support Python 3.8 because of resource dependency datrie which doesn't support Python 3.8; dropped from the PR
• stormpath-cli — deleted formula in stormpath-cli: delete #48350
• tox — fixed postinstall and test

pyinstaller says:

ValueError: script '/usr/local/Cellar/pyinstaller/3.5_1/libexec/lib/python/site-packages/easy_install.py' not found

I recommend merging everything except bumpversion and pyinstaller, rather than rerun the whole thing again. Let me know if you're okay with that, and I can do it.

Sounds good to me, let's do it.
Thanks @fxcoudert!

[fxcoudert]

It is done.

For reference: I merged everything with brew pull --bottle 48323, then rebased to remove the 4 unwanted commits (bumpversion, pyinstaller, and their two bottle commits), then logged into bintray to delete the bumpversion and pyinstaller bottles (so they won't be a problem later, when we actually bump revision on these formulas).
