Revert "Build wheel house during nodepool devstack caching"

This reverts commit 1f84dbb2ce2ae7ed50401299db499adb6e836ec0.

Reverting because this runs a significant portion of devstack during
image builds installing packages necessary to build the wheels. Instead
we should be building wheels and hosting them on our mirror. Then image
builds and jobs themselves can both use this mirror to either cache
wheels or install wheels.
