Deprecations and Removals - 21.0.0

• The Python discovery logic has been extracted into a standalone python-discovery package on PyPI (documentation <https://python-discovery.readthedocs.io/>_) and is now consumed as a dependency. If you previously imported discovery internals directly (e.g. from virtualenv.discovery.py_info import PythonInfo), switch to from python_discovery import PythonInfo. Backward-compatibility re-export shims are provided at virtualenv.discovery.py_info, virtualenv.discovery.py_spec, and virtualenv.discovery.cached_py_info, however these are considered unsupported and may be removed in a future release - by :user:gaborbernat. (:issue:3070)
