Use request naming for IP to fix filtering by IP
Use request naming for IP to fix filtering by IP

The naming of the IP field in the request metadata should be "clientIp"
as this is what we use in other notifiers. Changing this will fix the
problem of being unable to filter by "request ip" in the PHP notifier.
