When trying to use this services-wrapper.py on FreeBSD I was unable to connect to my database. When using the socket logic from the other wrapper python scripts it works fine. Streamline this wrapper with that same logic from poller-wrapper.py and discovery-wrapper.py.
If db_port is set in the config.php, services-wrapper will not work.
This fixes the issue and adds a check if db_port is set to be used as the DB port when connecting.
I used 'if SETTING in config' method as this is used below in the script.
Now with optparse (python 2.3+)
