The reroute command allocate has been split into two distinct commands allocate_replica and allocate_empty_primary. This was done as we introduced a new allocate_stale_primary command. The new allocate_replica command corresponds to the old allocate command with allow_primary set to false. The new allocate_empty_primary command corresponds to the old allocate command with allow_primary set to true.
