Clustering: DCN varies in normal and restart scenarios

Test Environment : Single Node Controller

For following case, DCN is received in normal operational condition and no DCN is received when the node gets restarted (ie. restoration is completed).

Checked if the registration for DCN happened consistently during restart and registration seems to have no issues

Normal Behavior

Path Scope Data Change DCN Received
========================================================================
/container/list BASE Add entry to list On per entry basis
/container/list SUBTREE Add entry to list On per entry basis

Restart Behavior

Path Scope Data Change DCN Received
========================================================================
/container/list BASE Add entry to list No DCN event Received
/container/list SUBTREE Add entry to list No DCN event Received

When normal DCN behavior is different from restart behavior apps which act on DCN behave differently when nodal restart occurs
