When the IPv6 is disabled on the node, we generally add the below in /etc/sysconfig/chronyd for the chronyd to work with IPv4.

OPTIONS="-4"

While we are using the rhel-system-roles.timesync role for the timesync purpose on the managed node, we do not have an option to mention OPTION="-4" 

Unfortunately, the template used for this (templates/chronyd.sysconfig.j2) hardcodes the "OPTIONS" parameter to remain empty.

We will need either one of the option to be added:
1. Add a setting to the timesync role to disable IPv6.
2. Add a parameter so I can set the "OPTIONS" parameter myself via a default value.
