updated wheel builder python app

This commit increases performance when building all of the python packages
that our systems depended on. This also provides the system a capability
to build specific versions of packages that may be required and or duplicated
throughout the various projects.

IE a particular project may require a specific version of a package to be
installed that may be a lower revision that what is already built.
