unlike our python code, we have no automatic style checking for
bash. For the most part, it's not a big deal, but errant whitespace
or incorrect indenting is sometimes annoying to have to -1 people's
patches for. Instead of constantly picking it up in manual review
maybe we can do better.
This is an uber hacky script which could be used to do just that.
./tools/bash8.py file1 file2 file3 ...
And it will show issues found with the files at hand. Lightly
tested in the existing devstack tree, it exposes a few issues that
we might want to think about.
This should be python 3 compatible, and includes argparse to provide
a basic '-h' support to explain how the command should be run.
