Enable custom roles
Beyond the composable services within roles requirement, there is a need to enable flexible definition of custom roles, e.g groups of nodes in addition to the fixed Controller, Compute and *Storage roles.
This will enable independently scaling certain services beyond the 3-controller topology, and also simplify integration of optional or 3rd party tools which require dedicated nodes (such as some SDN controller nodes).
