This commit adds the logic to detect a passed in volumeID is a migrated volume ID and if yes, the driver connect to the backend cluster and clean/delete the image. The logic only applied if its a migration volume ID. The migration volume ID carry the information like mons, pool and image name which is good enough for the driver to identify and connect to the backend cluster for its operations. migration volID format: <mig>_mons-<monsHash>_image-<imageUID>_<poolHash> Details on the hash values: * MonsHash: this carry a hash value (md5sum) which will be acted as the `clusterID` for the operations in this context. * ImageUID: this is the unique UUID generated by kubernetes for the created volume. * PoolHash: this is an encoded string of pool name.
