Fix scheduler on production infrastructure
Fix scheduler on production infrastructure

Apparently the long waits cause timeouts in the rabbitmq connections,
and pika doesn't handle reconnecting for us (laaaaaaaame!). Instead of
using a long-lived connection that will hit TCP timeouts, use a
short-lived one that will pretty much constantly have data going across
it, to avoid the timeouts, and the related socket issues. Win!
