Configure NTP Client for `timedatectl` via `systemd-timesyncd`

set_ntp_settings.yaml

# vim:ts=2:sts=2:sw=2:et
#===========================================================
# NTP Configuration Playbook
#===========================================================
# This script will remove the 'ntp' daemon from each server
# and properly configure the 'systemd-timesyncd' daemon so
# that 'timedatectl' uses a specific NTP server.  Remember
# to create a 'timesyncd.conf' file that holds your config
# in the same directory as this ansible playbook before
# running.
#-----------------------------------------------------------
# There are two categories managed: 'arch' and 'ubuntu'.
# When you create your hosts file, keep this in mind.
