Allow user to override pip cache location

Building a VM containing devstack is faster if you can save
the cache files for pip in a location that is not deleted
when the VM is rebuilt. This change allows the user to
set the PIP_DOWNLOAD_CACHE in their localrc file to point
to any directory writable by root, including a directory
mounted from the host containing the VM.
