// CSIDriver captures information about a Container Storage Interface (CSI)
// volume driver deployed on the cluster.
// CSI drivers do not need to create the CSIDriver object directly. Instead they may use the

// creates a CSIDriver object representing the driver.
// Kubernetes attach detach controller uses this object to determine whether attach is required.
