This provides the lib/lvol wrapper around blobstore's external snapshots. Later commits make this work with vbdev_lvol. The blobstore external snapshot implementation stores an opaque identifier in an internal xattr. Lvstore uses this to store the stringified UUID of the bdev that will act as the external snapshot. This is used by the newly introduced spdk_lvol_create_esnap_clone() to store the bdev UUID in the blob's metadata.
