Set static & dhcp sent ntp server ip on ethernet obj

Currently there is no way to differentiate between the Static
and DHCP assigned NTP servers at dbus

This commit adds StaticNTPServers peroperty to hold the static
configuration of NTP servers. This is a read-write property.
The existing NTPServer propery will hold both static and DHCP
assigned NTP servers. This is a read-only property.

The static and dhcp sent ntp server details are present in the
dbus object hosted by systemd-timesyncd service (mentioned in
Tested By section).

In this change, networkd fetches the ntp server details from the
timesyncd dbus object and set the "NTPServers" property with dhcp sent
ip and "StaticNTPServers" will be set from the configuration file.

Tested By:

* Change the ntp server ips in dhcp config file & restart dhcpd
* timesyncd dbus object contains the new list of ips as below:

* Since network configuration has changed, the service restarts and
ntp server details are loaded from timesyncd dbus object & config file,
and are set in dbus objects hosted by networkd.

         busctl introspect xyz.openbmc_project.Network /xyz/openbmc_project/network/eth1

* Ethernet interface network config files will be updated with NTP=<ip addresses> under [Network]
