CLOUDSTACK-7631: Log rotate on VR may fail as /etc/init.d/rsyslog does not anymore support reload option on debian wheezy
add conntrackd logrotate for systemvms, dont start conntrackd on logrotate if it isnt running
If for some reason dnsmasq.log does not exist anymore logrotate will create it with nobody as owner. This will prevent dnsmasq deamon from logging to that file.
