Title: feat(*): provision using CoreOS stable channel

CoreOS 494.3.0 was promoted to stable today, so Deis should be able to settle there. Provider IDs & AMIs were all updated except Rackspace, which hopefully refreshes their images later today.

Double-check IDs at https://coreos.com/docs/running-coreos/cloud-providers/ec2/ and https://coreos.com/docs/running-coreos/cloud-providers/google-compute-engine/. Refs #2613 and #2631.
