Consolidate package requirements about adapt

[clusterfudge]

I'm not fully aligned with this strategy; I've tried it in the past, and it actually results in some basic issues. The largest is that there is almost always an intentional difference between packaged build/runtime dependencies and test dependencies, and python does not have a better way of breaking these out.

For example, in #125 , we're introducing a dependency on flake8 and pytest for the build process. Those should not be dependencies of the released artifact, but also probably shouldn't only be specified in the github actions build file.

From the last round of "what's the best way to", I concluded two things:

• Only runtime requirements should exist in setup.py; this is instructs tools like pip how to resolve transitive dependencies, and should specifically be runtime dependencies.
• Development dependencies (testing tools, code generation, doc parsers) and runtime dependencies should exist in requirements.txt, so that any developer can easily git clone + pip install -r requirements.txt and be able to run tests.

I'm curious though, is this opinion in conflict with #124 ? Theoretically if source builds include test files, you would want to specify their dependencies somehow.

Adapt has the file test-requirements.txt which could be updated and used in the github-actions.

I've recently learned that the -r flag can be used in requirements files to include another file. so the test-requirements.txt could be updated to be

pytest
flake8
-r requirements.txt

(possibly renaming it to dev-requirements.txt or something)

There is also the option of having the setup.py called from the requirements file. Keeping the necessary requirements in the setup.py and dev requirements in requirements.txt.

Then another option that I've been looking at for mycroft-messagebus-client is to use the tests_require and test arguments for setup() to be able to call python setup.py test to perform the tests

oooooooohhhhhhhh! ✨
