Start releasing to PyPI

[martinb3]

We should start doing regular releases to PyPI so we can allow others to depend on this tool and force specific version requirements when they use it to test. This would also allow for others to depend on a specific major version when breaking changes happen in jetstream.

just a note: installing from pypi currently pulls in a very old version of troposphere:

WARNING: You are using pip version 20.0.2; however, version 20.1 is available.
You should consider upgrading via the '/home/steven/temp/venv/bin/python -m pip install --upgrade pip' command.

Which produces some unexpected results:

(venv) @sol ~/temp $ python -c "from troposphere import Sub"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name 'Sub' from 'troposphere' (/home/steven/temp/venv/lib/python3.8/site-packages/troposphere/__init__.py)

cloning the repo and installing that way works as expected.
