Add support to update NTP server list in network files

This provides following APIs:

SetNtpServer takes network device name and list of NTP server IP's or
hostnames and updates the corresponding  .network files with NTP= under
[Network] section.

Example:
[Network]
NTP = 1.2.3.4 time.org

UpdateUseNtpField takes a  string and updates all the available .network files
with either UseNtp=true or UseNtp=false depending on user input.

Example:

[DHCP]
UseNtp = false
