> *Motivation*
> A placement driver should provide a primary node for each replication group in all cluster nodes. The node will be used as a destination to send a replica request that should be processed by primary.
> *Implementation notes*
> The primary replicas are stored in Metastorage in keys with _prefix placementdriver.lease.holder_<REPLICATION_GROUP_ID>. Also, the key will be able to use to update list of primary nodes.
