SUSE: 2020:3737-1 Moderate: Python-pip, Python-scripttest Security Fix

This update for python-pip, python-scripttest fixes the following issues: - Update in SLE-15 (bsc#1175297, jsc#ECO-3035, jsc#PM-2318) python-pip was updated to 20.0.2: * Fix a regression in generation of compatibility tags * Rename an internal module, to avoid ImportErrors due to improper uninstallation * Switch to a dedicated CLI tool for vendoring dependencies. * Remove wheel tag calculation from pip and use packaging.tags. This should provide more tags ordered better than in prior releases. * Deprecate setup.py-based builds that do not generate an .egg-info directory. * The pip>=20 wheel cache is not retro-compatible with previous versions. Until pip 21.0, pip will continue to take advantage of existing legacy cache entries. * Deprecate undocumented --skip-requirements-regex option.
