While the change in https://review.opendev.org/c/starlingx/ptp-notification-armada-app/+/860494 solved the problem of moving PTP tracking service across nodes for notification API v1, it didn't managed properly for v2. This change fixes the problem for v2 while improves the solution for v1. Test Plan: PASS: Both v1 & v2 of API tested for pull of current states. Closes-Bug: #1991793 Signed-off-by: Douglas Henrique Koerich <douglashenrique.koerich@windriver.com> Change-Id: I1afe8a864e8cda909743c2e91b93a7bc8dda66e8
