> Currently, when restoring a state store in a Kafka Streams application, we put one key-value
at a time into the store.  
> This task aims to make this recovery more efficient by creating a new interface with
"restoreAll" functionality allowing for bulk writes by the underlying state store implementation.
> The proposal will also add "beginRestore" and "endRestore" callback methods potentially
used for 
>     Tracking when the bulk restoration process begins and ends.
>     Keeping track of the number of records and last offset restored.
