With the disabling of the NtpPool configuration (https://review.openstack.org/#/c/620981/), we are only configuring a single ntp source. This can lead to NTP time sync failures if the one server that is picked is not currently available. We need to specify multiple default NtpServer entries in order to prevent the time sync from failing if we are not going to use the NtpPool configuration.
