Support time synchronization on hosts
This change introduces functionality to synchronize
infra/kube nodes' clock with external NTP authority.
Configuring external time source is optional, however
default behaviour will be to setup NTP time source on
infra-node and sync kube-nodes clock with it.
It's also possible to setup custom time zone.
