Evgeniy Kochetov b7bfa50468 blob: Use bdev copy command in CoW flow if supported 
Copy-on-write happens when cluster is written for the first time for
thin provisioned volume. Currently it is implemented as two separate
requests to underlying bdev: read of the whole cluster to bounce
buffer and then write of this buffer to the new location on the same
underlying bdev.

This patch improves copy-on-write flow by utilizing copy command of
underlying bdev if it is supported. In this case we have just one
request to bdev and don't need the bounce buffer.
