FCOS uses upstream NTP servers

FCOS is using: pool 2.fedora.pool.ntp.org iburst which is not avaible in the TN.

We need to configure chronyd with dhcp or configure with the TN NTP servers:

#pool 2.fedora.pool.ntp.org iburst
server 172.18.16.69 iburst
server 172.18.17.69 iburst

GPN:

server ip-time-0.cern.ch iburst
server ip-time-1.cern.ch iburst
server ip-time-2.cern.ch iburst

TN:

server ip-time-3.cern.ch iburst
server ip-time-4.cern.ch iburst
server ip-time-5.cern.ch iburst
