Chrony NTP servers configuration is out-of-date when compared to Leap 15-3 JeOS

[FroggyFlox]

This is another follow-up to #49.
Currently, we define the NTP servers for chrony to use while building the installer as follows:

rockstor-installer/config.sh

Lines 114 to 125 in ca6a6df

	#=====================================
	# Enable chrony if installed
	#-------------------------------------
	if [ -f /etc/chrony.conf ]; then
	# chronyc sits at 100% CPU even if chronyd service is disable
	# Looks like: https://github.com/balena-os/meta-balena/issues/1360
	# This should help once sorted; for now not installing chronyd (shame)
	# suseInsertService chronyd
	for i in 0 1 2 3; do
	echo "server $i.opensuse.pool.ntp.org iburst"
	done > /etc/chrony.d/opensuse.conf
	fi

However, Leap 15-3 JeOS now uses a much more streamlined setup using SUSE NTP pool:

#=====================================
# Enable chrony if installed
#-------------------------------------
if [ -f /etc/chrony.conf ]; then
	suseInsertService chronyd
fi

This results in:

# ls -lah /etc/chrony.d/pool.conf
-rw-r--r-- 1 root root 32 May 27  2020 /etc/chrony.d/pool.conf

... defining the SUSE pool:

# cat /etc/chrony.d/pool.conf
pool 2.suse.pool.ntp.org iburst

Interestingly, this file is provided by:

# zypper se --provides /etc/chrony.d/pool.conf

... which itself was installed as part of chrony, I believe:

It's interesting to see it pulls down chrony-pool-suse and not chrony-pool-opensuse... another way Leap and SLE are getting closer?

Just done a quick check and recent builds do actually install the opensuse variant but it also looks like they are now identical as they share exact info. Likely one is now a link to the other.

I'll check again to see if this changes over when we use the kiwi-ng build-in for activating this service.

localhost:~ # rpm -ql chrony-pool-openSUSE
/etc/chrony.d/pool.conf
