> Ignite must provide an option to snapshot only primary copies of partitions.
> This will improve:
>   * snapshot creation time.
>   * disk usage during snapshot creation.
>   * space amount to store snapshot.
> This will lead to the following disadvantages during restore process:
>   * rebalance (can be omitted with custom file copy script and cellular affinity)
>   * index.bin rebuild - performance improved in IGNITE-18271
