tests: use tox and overhaul project testing To properly test the project commands, it would be best to have a fresh west bootstrapper package created and installed on PATH, so it could be used to run commands exactly as they'd happen if we package and ship the working tree. To make that easier, add a dependency on tox and use it for testing: https://tox.readthedocs.io/en/latest/ From now on, we'll test west by running 'tox' from the repository root. This has several advantages over running pytest directly: - "Just run tox": there are no longer any differences in test invocation between POSIX OSes and Windows. - tox creates an sdist package of the current tree using our setup.py and installs it into a new virtual environment, then runs tests there. This removes interference from other packages installed on the host (like released bootstrappers that are also installed) - we get to run multiple shell commands in order, should that ever be needed, in our test procedures in a way that won't affect users With that done, we can re-work the multirepo command testing to invoke the bootstrapper in the virtual environment, adding various tests and filling in longstanding testing gaps by adding increased checking of the results (currently, much of the testing just checks whether commands do or do not error out, which isn't enough). These changes were made with a view towards the upcoming changes which are planned before releasing west "into the wild": the test case code should be mostly the same before and after the changes, so this serves as a good baseline against regressions introduced by those upcoming changes.
