Scaling

A storage cluster scales out by adding Kubernetes workers as storage nodes, which adds capacity and performance at the same time. New workers are described in a growth ClusterDeploymentConfig that names the existing cluster, either written by hand or drafted by a discovery run. The cluster keeps serving I/O throughout, and the data is rebalanced onto the new devices afterward.
