[jira] [Updated] (IGNITE-18961) Implement lease prolongation on placement driver side

     [ https://issues.apache.org/jira/browse/IGNITE-18961?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vladislav Pyatkov updated IGNITE-18961:
---------------------------------------
    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.
