------------------------------------------
As SCM supports HA, for now we can leave it.
But it is good to bring this for non-HA clusters.
> Enable sync option for SCM non-HA

> In SCM non-HA when we use rocksdb put, it should write to DB with sync turned
> on. As in non-HA when power failure/system crashes, the operations which are
> acknowledged by SCM might be lost in this kind of scenario. (As in rocks DB
> with Sync false, the flush is asynchronous and it will not persist to storage
> system)
>
> In HA, this is not a problem because the guarantee is provided by ratis and
> ratis logs.
