This adds a test suite for fifloader (renamed fifloader.py for
test sanity). It adds JSON Schema form schemas for both FIF and
upstream openQA template data, and has fifloader (optionally,
but by default) validate both input and output data against the
schemas. It also adds a tox.ini configured to run the fifloader
tests, use fifloader to validate the template files, and do diff
coverage and lint checks. It also adjusts the Zuul config to run
tox instead of the test job.
There are also some pylint cleanups, since the new tests run
pylint.
fifcheck, fifconverter and tojson.pm are removed, as they were
mainly only needed for one-time conversion of the old format
templates; now they are in the git history we can always recover
them if we need them.
Along with all this I updated the README a bit to explain some
of it (and explain FIF better), and to explicitly state that this
repo is GPLv2+ licensed, and added GPL headers to some of the
files.
