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().

spdk_lvol_get_by_uuid() allows lookup of lvols by the lvol's uuid.
spdk_lvol_get_by_names() allows lookup of lvols by the lvol's lvstore
name and lvol name.

Add an interator that calls a callback for each clone of a snapshot
volume. This follows the typical pattern of stopping iteration when the
callback returns non-zero.

This introduces spdk_lvs_notify_hotplug() to trigger the lvstore to call
the appropriate lvstore's esnap_bs_dev_create() callback for each esnap
clone lvol that is missing the device identified by esnap_id.

If an lvol is opened in degraded mode, keep track of the missing esnap
IDs and which lvols need them. A future commit will make use of this
information to bring lvols out of degraded mode when their external
snapshot device appears.

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.

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.
