[syslog-ng] request for testing: logrotate scripts in Fedora/RHEL packages

The RHEL7 packages work correctly and do not have any conflict with rsyslog.

The RHEL8 package is going to give me some problems. Our syslog-ng 
configuration produces files different than the default, so we have 
configured the logrotate file appropriately. When the RPM update process 
runs the syslog-ng package will be updated and because we do not have 
the rsyslog package installed, the syslog-ng-logrotate package will be 

This process will remove my custom /etc/logrotate.d/syslog file and 
create a new default /etc/logrotate.d/syslog-ng

This will break by logrotate configuration on all systems that 
auto-update the RPM packages.

I think the correct approach would be to move the 
/etc/logrotate.d/syslog file to /etc/logrotate.d/syslog-ng when the 
syslog-ng-logrotate package is installed for the first time.
