The python/build folder contents are completely unrelated to the ovs
python bindings. These files are only used during the build for various
subsystems (docs, man pages, code generation, etc.).
Having that folder in that location prevents from running:
cd python && python3 -m build
Which is a way to generate PEP517 compatible source archives and binary
wheel packages.
Rename that folder to ovs_build_helpers which is more explicit. Update
all imports accordingly.

Python 2 reaches end-of-life on January 1, 2020, which is only
a few months away. This means that OVS needs to stop depending
on in the next release that should occur roughly that same time.
Therefore, this commit removes all support for Python 2. It
also makes Python 3 a mandatory build dependency.
Some of the interesting consequences:
- HAVE_PYTHON, HAVE_PYTHON2, and HAVE_PYTHON3 conditionals have
been removed, since we now know that Python3 is available.
- $PYTHON and $PYTHON2 are removed, and $PYTHON3 is always
available.
- Many tests for Python 2 support have been removed, and the ones
that depended on Python 3 now run unconditionally. This allowed
several macros in the testsuite to be removed, making the code
clearer. This does make some of the changes to the testsuite
files large due to indentation level changes.
- #! lines for Python now use /usr/bin/python3 instead of
/usr/bin/python.
- Packaging depends on Python 3 packages.

Perl is unfashionable and Python is more widely available and understood,
so this commit converts one of the OVS uses of Perl into Python.
