The original issue has been exposed due to CloudStack VR would modify the
dnsmasq.leases, thus make it unsync with dnsmasq's memory lease.
Make the modification to let dnsmasq handle the lease file if dhcp_release is
available.

All (almost) files belonging to the systemvm aer now centralize in the systemvm directory. The code for the separate functions is still in the services directory. This will make the code easier to understand and makes it clear that the systemvm is a separate item. It alos means that it can be excluded from the build entirely by not adding the systemvm profile, this will speed up the compiles somewhat.
