Composable overcloud upgrades
The core idea is to switch upgrades from node-focused approach to service-focused approach. Instead of constructing the upgrades workflow and code around which nodes to upgrade, we'd base them around which services to upgrade, and a service upgrade would be cloud-wide, touching all nodes where such service is deployed. This might mean a complete rewrite of our upgrades approach.
