Enable all tests on OSX (disable docker tests only in Github Action CI OSX runners)

[emersonknapp]

Description

Currently, the tests in the test suite that use Docker are disabled on OSX. This isn't a hard requirement, it is only the case because the GitHub Action CI OSX runner hosts don't have (and won't have) Docker. Instead of disabling universally, allow configuration (via environment variable?) to disable Docker-based tests at runtime.

This way, development on OSX runs full test suite.

• Developer on OSX running tox -e py runs entire test suite by default.
• Action CI on OSX can disable the Docker-based tests at runtime

Implementation Notes / Suggestions

Maybe an environment variable?
