Sync time on cfg01 node before tempest

- sync time again on all the nodes including cfg01
- check if the services 'maas-rackd' and 'maas-regiond' are
  present on the node. if yes - disable the services while
  time is synchronized
- execute salt_actions.sync_time() also before the tempest
  is started
- remove the class override_ntp_virtual because it disables
  the ntp client on cfg01.
