block: Add backend_defaults property
backend_defaults property allow users to control if default block
properties should be decided with backend information.
If it is off, any backend information will be discarded, which is
suitable if you plan to perform live migration to a different disk backend.
If it is on, a block device may utilize backend information more
aggressively.
By default, it is auto, which uses backend information for block
sizes and ignores the others, which is consistent with the older
versions.
