check-compose: switch to fedmsg-hub based fedmsg consumer

I'm switching the misc. QA fedmsg consumers over to using fedmsg-
hub, due to https://github.com/fedora-infra/fedmsg/issues/365 .
So we need to adjust how we install check-compose, install a
config file to enable the consumer, and also set up the fedmsg
base and hub roles on the openqa server boxes (which do the
check-compose job ATM).
