Confluent Docker Images are failing to build:

Due to https://github.com/tobgu/pyrsistent/pull/206 - If the maintainers yank the 0.17.0 release & add a python_requires & re-publish, then we won't have to take an action, otherwise this will be required.

We're somewhat fixed now that they've yanked all the 0.17.* releases: https://pypi.org/project/pyrsistent/#history

But I'm keeping this around if it pops up again.

Actually looking at the 5.4.x common-docker logs:

02:08:45  [INFO] Collecting pyrsistent>=0.14.0
02:08:45  [INFO]   Downloading pyrsistent-0.17.1.tar.gz (106 kB)
02:08:45  [INFO] ERROR: Package 'pyrsistent' requires a different Python: 2.7.9 not in '>=3.5'

This is needed now.
