[System Tests] Please, add sync_ceph_time method to all tests with check_ceph_health method

We have 'ceph_ha_restart' test in test_restart.py which failed with timeout

Please, add 'sync_ceph_time' method to this test and check where we need to add it too.
Probably to all tests with restart and check ceph health check
