The current koji integration uses the koji Python client package. The downside of it is that we're using a threadpool to execute the koji requests to XMLRPC concurrently. This can be expensive and won't scale more than what we're bound by the CPU of the host machine.

Alternatives:

* Don't use a thread pool and the koji client library, but instead use the requests solution from Bug 1388265
* Write your own XMLRPC asyncio library??
