Configuring NTP multicast mode

The multicast server periodically sends NTP multicast messages to multicast clients, which send replies
after they receive the messages and synchronize their local clocks.
For devices working in multicast mode, configure both the server and clients. The NTP multicast mode
must be configured in the specific interface view.
