Code comments currently claim the default iscsi mount path as
kubernetes.io/pod/iscsi/<portal>-iqn-<iqn>-lun-<id>, however actual
path being used is
kubernetes.io/iscsi/iscsi/<portal>-iqn-<iqn>-lun-<id>
This leads to ultimate path being similar to this :
kubernetes.io/iscsi/iscsi/...iqn-iqn...-lun-N
Both iscsi and iqn are repated twice for no reason, since "iqn" is
required by spec to be part of an iqn. This is also wrong on
multiple leves as actual allowed naming formats are :
iqn.2001-04.com.example:storage:diskarrays-sn-a8675309
eui.02004567A425678D
(RFC 3720 3.2.6.3)
and in the second case "iqn-eui" in the path would be misleading.
Change this to a more reasonable path of
kubernetes.io/iscsi/<portal>-<iqn>-lun-<id>
which also aligns up with how the /dev/by-path and sysfs entries
are created for iscsi devices on linux

Update iSCSI README and sample json file
There seems to have been quite a skew in recent updates to these
files adding in wrong info or info that no longer lines up the
sample config with the README.
Fixed the following issues :
* Fix discrepancy in samples json using initiator iqn from previous
linked example as target iqn (which was just wrong)
* Generate sample output and README from the same json config provided.
* Remove recommendation to edit initiator name, this is not required
(open-iscsi warns against editing this manually and provides a utility
for the same)
* Update docker inspect command to one that works.
* Use separate LUNs for separate mount points instead of re-using.
- Put the link for setting up the target before initiator link.
- Add a comment about removing the partition created in the linked
tutorial.
- Change the settings in the pod to resemble those you would if you
follow the tutorial
