This introduces support for the options to customize the image volume cache feature. This feature is added to the default class as well as the defined resource type for each volume driver, so that users can configure the global options as well as the backend specific options. Note that rbd driver and vmware driver are intentionally excluded, because for these drivers the specific image store drivers are more popular method to use in-storage copy when creating a volume from an image.
