<p>VolumeConfiguration contains <em>all</em> enumerated flags meant to configure all volume
plugins. From this config, the controller-manager binary will create many instances of
volume.VolumeConfig, each containing only the configuration needed for that plugin which
are then passed to the appropriate plugin. The ControllerManager binary is the only part
of the code which knows what plugins are supported and which flags correspond to each plugin.</p>
