Add support for NTP server

Description

Currently Infix only supports running chronyd as an NTP client via configuration in ietf-system.yang.

This is a proposal to use RFC 9249, in a stripped down form, to add NTP server support as well using chronyd.

Original tree view, from the RFC, is available here: https://github.com/dhruvdhody/ietf-yang/blob/master/ietf-ntp.tree

Tree View

This is an initial, heavily cut down (deviated), tree view based on the RFC.

module: ietf-ntp
  +--rw ntp!
     +--rw port?                  inet:port-number {ntp-port}?
     +--rw refclock-master!
     |  +--rw master-stratum?     ntp-stratum
     +--rw interfaces
     |  +--rw interface* [name]
     |     +--rw name             if:interface-ref
     +--ro ntp-statistics
        +--ro packet-sent?        yang:counter32
        +--ro packet-sent-fail?   yang:counter32
        +--ro packet-received?    yang:counter32
        +--ro packet-dropped?     yang:counter32

CCB decision: great feature, needs to be investigated further which model to use though. Aiming for milestone: future, for now.

From the ietf-ntp model:

 container ntp {
    when 'false() = boolean(/sys:system/sys:ntp)' {
      description
        "Applicable when the system /sys/ntp/ is not used.";
    }
    presence "NTP is enabled and system should attempt to
              synchronize the system clock with an NTP server
              from the 'ntp/associations' list.";
    description
      "Configuration parameters for NTP";
    leaf port {
      if-feature "ntp-port";
      type inet:port-number {
        range "123 | 1024..max";
      }
      default "123";
      description
        "Specify the port used to send and receive NTP packets.";
