Use python3 for running Ansible in init

Because the python docker container installs python to a location other
than /usr/bin, ansible doesn't know it have python3 available. Setting
this flag allows the build to use python3 and fix a pip error.

An extra setting ANSIBLE_STDOUT_CALLBACK=yaml is added to add clearer
output when running ansible, and can be overridden in the
docker-compose.yaml file.
