SolidFire driver introduced a clone image feature in Kilo release[1] where we would create a cache volume with volume ID same as of image ID to create volume from image efficiently by cloning from that cached volume. This feature worked same as the image cache feature we have in cinder so it was deprecated in queens[2] and removed in train[3] in favor of image cache feature provided by cinder. However, we still kept compatibility code if users had solidfire cached volumes to still take advantage of those to create efficient volume from images. In the current master (Yoga), we can safely assume that people have moved to using the image cache feature of cinder since the solidfire options to enable efficient cloning doesn't exist since train release. This patch removes the remaining code around this feature as it doesn't provide any additional benefit and we also log an ERROR message unnecessarily confusing the operators for every create volume from image request (details are in the linked launchpad bug).
