> We have a system property named "IGNITE_PDS_WAL_REBALANCE_THRESHOLD", that determines a count of entries of partition starting from which cluster will try applying historical rebalance for that partition.
>  But the system property is not convenient to use and is hidden from most part of users.
> I propose the creation of a new DMS property *wal.rebalance.threshold* instead of a system property.
> The next algorithm will be used:
>  # On node start *wal.rebalance.threshold* property will be checked.
>  # If there is no value, then the old system property *IGNITE_PDS_WAL_REBALANCE_THRESHOLD* value will be written to DMS.
>  # If a system property is not defined then the default value from java will be written to DMS (*500*).
>  # On property check print to log value and source of value.
> Mark the system property *IGNITE_PDS_WAL_REBALANCE_THRESHOLD* as deprecated.
