Add and enable pyflakes3 on console_conf, subiquity, subiquitycore and tests.
Replace NOQA markers with __all__ declarations for module imports.
Replace some obvious deadcode that voilates flake8, separate pass for removing
dead code rather than commenting will be handled later.
And a custom Welcome screen to boot; to show the overriding of settings.
