When the region to copy is partitioned and
the gateway sender is parallel, each gateway
sender sends the primary copies of the
buckets in that server.
Deserialization of the entries is also avoided.

…al gw sender.

When the region to copy is partitioned and the
gateway sender is serial, every server will
use the local gateway sender to copy the
local primary entries in it.

Also the output of the command when the region
is replicated has been improved so that
only the output of the server that copies entries
(the one hosting the primary sender) will be
printed by the command.
