CreateRepo Performance Improvements

Introduction

The Fedora-ARM build farm consists of the koji-hub/koji-web system (on HongKong, an x86_64 machine) and a group of ARM builders. HongKong also handles the CreateRepo tasks, which heavily load that machine. It might make sense to move those tasks to another machine, but doing so makes the CreateRepo jobs take a lot longer (15 minutes on HongKong vs. 55 minutes on another x86_64 server). This is presumably due to the overhead of sharing files between HongKong and the other server over NFS on the 100 Mbps Seneca network.
