> Retries of transaction on recovery should be idempotent, this means that TxStateStorage.compareAndSet should return true not only when actualState == expectedState but also when actualState == stateToSet. 
> Commit timestamp should be generated on transaction coordinator, only in case of commit, and added to TxFinishReplicaRequest. It should be checked on CAS to check actualState == stateToSet.
