> Defragmentation is executed in a single thread right now. It makes sense to
> execute the defragmentation of partitions of one group in parallel.
> Several parameters will be added to the defragmentation configuration:
> * checkpointThreadPoolSize - the size of thread pool which would be used by
> checkpointer for writing defragmented pages to disk.
> * executionThreadPoolSize - the size of the thread pool which shows how many
> partitions maximum can be defragmented at the same time.
