Description

With the upgrade to Python 3 in the Mesos codebase builds which rely on docker images started to fail since they were missing a `python3` installation.

We fixed those issues for most of the Docker images in https://issues.apache.org/jira/browse/MESOS-8957. We still miss Python 3 on the Ubuntu-16.04-arm image which can be found in `support/mesos-build/ubuntu-16.04-arm`.
