Fix for Bug NMS-7106

If a target node is rebooted the RRD/JRB files contains spikes because

Enhancing the XML representation of a monitored service.

Here is an example:

<service down="false" id="37" status="A" statusLong="Managed">
  <ipInterfaceId>31</ipInterfaceId>
  <serviceType id="4">
    <name>POP3</name>
  </serviceType>
</service>

The new attributes are:

- down
- statusLong
