Migration Plugin

Optimize content migration queries to avoid sorts

• Use select_related instead of prefetch_related to get everything in one query
• Use .iterator() instead of chunked_iterator() which required an additional sort operation

The result is not much faster on my dev machine, but much faster on the Katello box w/ HDD.
