>             Project: Ignite
>          Issue Type: Improvement
>            Reporter: Denis Chudov

> *Motivation*
> As for now, RW requests to primary replica (see calls of `ReplicaService#invoke` ) are sent to raft leader, for which the refresh leader operation is needed. In presence of placement driver which is responsible for assigning primary replicas, this is not needed, the request can be sent directly to primary replica node. 
> Th information about primary replicas assigned by placement driver should be available on every node after IGNITE-18859 . This task is about switching primary replica calls and eliminating excessive code related to refreshing leader of raft group.
> *Definition of done*
> Requests to primary replica are made to those nodes that are assigned by placement driver, and no related Raft calls are made.
