iser_ip_address is not configured with the storage network address

The iser_ip_address parameter in /etc/cinder/cinder.conf has a wrong value.
This parameter has to be configured with the storage endpoint address, since it is no longer inherits the iscsi_ip_address by default.
Currently it uses the $my_ip value, which is not capable to work with RDMA transport (with its default value).
