[Tarantool-patches] [PATCH v2 1/4] box: expose box_is_orphan method

[sergepetrenko <sergepetrenko@tarantool.org>]

From: Serge Petrenko <sergepetrenko@tarantool.org>

is_orphan status check is needed by applier in order to not re-apply
local instance rows coming from the replica after replication has
synced.

Prerequisite #4739
