Remove my_ip from cinder.conf
Remove my_ip from cinder.conf

The current issue is that if we deploy c-vol service on a separate
machine, my_ip and SERVICE_HOST will be different, because my_ip is
the machine where c-vol service is running and SERVICE_HOST points
to the machine where the cinder api service is running. If my_ip of
c-vol in cinder.conf is set to the IP of c-api, it will cause the
issue that the volume is unable to attach. The issue can be resolved
by removing my_ip from cinder.conf.
