blobstore: implement spdk_bs_grow and bdev_lvol_grow_lvstore RPC The bdev_lvol_grow_lvstore will grow the lvstore size if the undering bdev size is increased. It invokes spdk_bs_grow internally. The spdk_bs_grow will extend the used_clusters bitmap. If there is no enough space resereved for the used_clusters bitmap, the api will fail. The reserved space was calculated according to the num_md_pages at blobstore creating time.

lvol: add support for external snapshots 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.

lvol: add spdk_lvol_is_degraded This is mostly a wrapper around spdk_blob_is_degraded(), but it also performs a NULL check on lvol->blob. Since an lvol without a blob cannot perform IO, this condition returns true. The two callers of spdk_blob_is_degraded() in vbdev_lvol.c have been updated to use spdk_lvol_is_degraded().

A future commit will make use of this information to bring lvols out of degraded mode when their external snapshot device appears.
