Remote gets caused by writes could be replicated only to the primary owner

For write operations that need the previous value, a write CH-only owner that doesn't have a key locally will attempt to retrieve the key from the read CH-owners.

Sending the remote get command to all the previous owners will create extra load on the cluster during state transfer, so it should be more efficient to send the remote get only to the primary owner. Even though the latency of some write operations will be higher, the average latency should be better.
