Beginning RC1.0 / 0.12.0, component YAMLs will require the currently unused version field.
This version field denotes the schema version of a component, (ie. pubsub.redis).

All components will be version with v1 to start with. Once a new version of a component increments (ie. v2), a new code package v2 will be created for the component in components-contrib repo and registered in the dapr runtime.
