Add support for open-iscsi transports.

Browse Source 
This enables use of software or hardware transports viz. be2iscsi,
bnx2i, cxgb3i, cxgb4i, qla4xx, iser and ocs. The default transport
(tcp) happens to be called "default".

Use of non-default transports changes the disk path to the following format:
/dev/disk/by-path/pci-<pci_id>-ip-<portal>-iscsi-<iqn>-lun-<lun_id>

Once you have installed iSCSI initiator and new Kubernetes, you can create a pod based on the example *iscsi.json*. In the pod JSON, you need to provide *targetPortal* (the iSCSI target's **IP** address and *port* if not the default port 3260), target's *iqn*, *lun*, and the type of the filesystem that has been created on the lun, and *readOnly* boolean. No initiator information is required.
If you want to use an iSCSI offload card or other open-iscsi transports besides tcp, setup an iSCSI interface and provide *iscsiInterface* in the pod JSON. The default name for an iscsi iface (open-iscsi parameter iface.iscsi\_ifacename) is in the format transport\_name.hwaddress when generated by iscsiadm. See [open-iscsi](http://www.open-iscsi.org/docs/README) or [openstack](http://docs.openstack.org/kilo/config-reference/content/iscsi-iface-config.html) for detailed configuration information.
**Note:** If you have followed the instructions in the links above you
may have partitioned the device, the iSCSI volume plugin does not
currently support partitions so format the device as one partition.
