> In 0.98, it seems the snapshot layout version could be configured by "hbase.snapshot.format.version".
However, SnapshotManager does not set snapshotLayoutVersion in its initialize(...) method
so that it always creates snapshot with latest layout format even when "hbase.snapshot.format.version"
is set to SnapshotManifestV1.DESCRIPTOR_VERSION in configuration.
