Nova API

1. In the node-specific hiera, disable the services at the first node you would like to upgrade with the keys

   1. apache::service_ensure: 'stopped'

2. Run puppet with the train modules/tags
3. Run apt-get purge python-cinderclient && dist-upgrade && apt-get autoremove

4. Run nova-manage api_db sync
5. Run nova-manage db sync
6. Re-enable placement API on the upgraded node:
   
   1. Remove apache::service_ensure: 'stopped' from the upgraded node's hiera file
7. Upgrade the rest of the nodes (basically run step 1-3, re-run puppet and restart nova-api and apache2)
