Specify multiple NtpServers by default

Browse Source 
The NtpServer default set now includes multiple pool.ntp.org hosts to
ensure that the time can be properly synced during the deployment.
Having only a single timesource can lead to deployment failures if the
time source is unavailable during the deployment. It is recommended
that you either set multiple NtpServers or use the NtpPool
configuration to ensure that enough time sources are available for the
hosts. Note that the NtpPool configuration is only available when using
chrony.
