chrony: wrong postrotate command

The current command is

PASSWORD=`awk '$1 ~ /^1$/ {print $2; exit}' /etc/chrony/chrony.keys`
cat << EOF | /usr/bin/chronyc | sed '/^200 OK$/d'
password $PASSWORD
cyclelogs
EOF

However since chrony 2.2 (the current version is 3.5) the password command does nothing and indeed when running the above manually you get Authentication is no longer supported.

There is an example of a logrotate conf on chrony's git repo that could be used.
