Vladislav Pyatkov updated IGNITE-18859:
---------------------------------------
    Description: 
*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.". Also, the key will be able to use to update list of primary nodes.
