Description

A part of replication groups' processing logic, described in IGNITE-18742 should be the lease prolongation. 

Placement driver should prolong existing leases, saved to local in-memory map, which lease time is going to expire. Let say, the lease should be prolonged when there is less than leaseInterval / 2 time left before expiration. Prolongation should be done via making meta storage invoke, without direct communication with replicas.
