add ntp config module

Add support for installing and configuring ntp service, exposing the
minimum config of servers or pools to be added. If none are defined
then fallback on generating a list of pools by distro hosted at
pool.ntp.org (which matches what's found in the default ntp.conf
shipped in the respective distro).
