Make use of new fedmsgs... or not #43

The FCOS pipeline now broadcasts a fedmsg whenever stream metadata changes: https://github.com/coreos/coreos-assembler/blob/93b7a510457ffe8f0cd9233db9eafd92ae26c8fe/src/cosalib/fedora_messaging_request.py#L84

Example msg:

https://apps.fedoraproject.org/datagrepper/id?id=2020-5c429b71-ae65-4b50-ad7d-432ce1126244&is_raw=true&size=extra-large

{
  "topic": "org.fedoraproject.prod.coreos.stream.metadata.update", 
  "headers": {}, 
  "msg": {
    "stream": "stable"
  }
}

Cincinnati could use this to optimize its refreshes and lower the polling frequency so it's just a fallback mechanism.
