                 Key: HDDS-5169
                 URL: https://issues.apache.org/jira/browse/HDDS-5169

During snapshot installation, notifyInstallSnapshot should download snapshot from leader.

Once the future is complete, Ratis puts state machine to pause, and reloadStateMachine which sets state machine updater to reload and do reinitializeStateMachine.

In-state machine reinitialize replace the DB checkpoint and make things ready to work with this new snapshot.
