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_<REPLICATION_GROUP_ID>. Also, the key will be able
to use to update list of primary nodes.
