Description

Currenlly txState(PENDING|ABORTED|COMMITED) is updated within all enlisted partitions which is not an atomic solution. According to new tx design it's required to replicate tx state with single partition only.
As a prerequisite persisted replicated TxnStateStore should be introduced https://issues.apache.org/jira/browse/IGNITE-15931
Such introduction will allow to rework existing tx implementaiton in order to store txState only within single partition.

instead of using

partId = abs(txId.hashCode() % partCnt) 

we might use any other idempotent funtion, e.g. first partition of first enlisted key.
