This allows us to remove the sudo from the tox molecule environment, since
the install-docker role correctly adds the zuul user to the docker group.

Adds the following zuul job:
kayobe-tox-molecule
It runs ansible role tests using the molecule framework.
Note that we are currently running tox as root to work around issues
with applying docker group membership in the Zuul CI environment.
The ubuntu-1604 platform has been removed because the job takes a long
time to run even on one platform.
