Increase usefulness of openstack-base

Just like last cycle, I ran all of the requirements and found the
packages that were installed >=10 times throughout our containers. By
combining them in the openstack-base we reduce the size of the images
by ~600MB (10%) and decrease build time by a measurable amount (5-10m
in the case of Centos)

TrivialFix
