Hello !

Would be great to have a playbook to upgrade system parts of an 
OpenStack Cloud !
With OpenStack Ansible : LXC containers and hosts.

It would be awesome to do a controlled rolling reboot of hosts when 

Different conditions to check :
- for controllers : check galera status...
- for compute nodes : disable compute node and live-evacuate 
- for storage : with Ceph : set no out...

I know, I can do it and contribute, but perhaps someone already has 
something similar ?
It could be hosted in one of these projects :
- https://git.openstack.org/cgit/openstack/openstack-ansible-ops

(Why already to project for the same goal ?)
