Log an event for each Service Status change (#8968)

Hello

Here is a proposal for a pièce of code to log (using log_events) each service status change onto the device itself. 

Let me know if we should create the "getStatusText()" function to convert the int to "OK", "Critical" etc etc . I searched for such a function but did not find it. 

I also add to use a hack for the SQL cause it would prevent the device_id valueto be available in the resulting $service when device_attribs is empty for the device. If you have a better way to suggest, I'll be happy to use it.
