TODOs

• The deployment/upgrade process needs to be documented in more than just the release notes.
  • dansmith was going to work on a blog post to start this.
  • alaski's older docs patch (which is probably out of date now but might be useful) is here: https://review.openstack.org/#/c/267153/
• Integrate the 'nova-status upgrade check' CLI into the CI/QA system (grenade).
• Older tracking etherpads (these may be out of date):
