Run packer against a specific builder

As preparation to enable the ability to configure multiple builders
in a single packer template, we need to enable the ability in the
job to select which builder to run.

This patch sets up a new variable "packer-builder" which is used to
select the builder definition in the templates file.

Defaulting to "openstack" as that's the most common use case at the
moment.
