The yum stuff only happens in the centos include in ansible, it's not
necessary in the ubuntu version, which uses a different ansible include.
An extra test for the record... manual run of the ubuntu14 development
environment:
building ubuntu14 (measuring start to end of ansible logs)
without cache: 45m13
with cache populated: 28m57
so won't change the world, but will hopefully save some coffee during
dev-test cycles.
