It's a kolla issue and they way project build images. Calling yum
install in Dockerfile is not the best idea (you endup with multiple
dependent packages put into the single image layer). Having some good
DSL would mean that you can place each package into separate image
layer (ie: RUN rpm -i ./python-nova-XXXX.rpm) and take advantage of
that during build (reusing cached layers).
