This removes some old skylib/zlib deps, moves all Go repositories to a
separate file, and in general does a small cleanup pass on external
repository magic.

python_rules is completely broken when it comes to py2/py3 support.
Here, we replace it with native python rules from new Bazel versions [1] and rules_pip for PyPI dependencies [2].
rules_pip is somewhat little known and experimental, but it seems to work much better than what we had previously.
We also unpin rules_docker and fix .bazelrc to force Bazel into Python 2 mode - hopefully, this repo will now work
fine under operating systems where `python` is python2 (as the standard dictates).
