Release note (performance improvement): Adds delegated snapshots which
can reduce WAN traffic for snapshot movement. If there is another
replica for this range with a closer locality than the delegate, the
leaseholder will attempt to have that delegate send the snapshot. This
is particularly useful in the case of a decommission of a node where
most snapshots are transferred to another replica in the same locality.
