Bye-bye iSCSI deploy, you served us well
The iSCSI deploy was very easy to start with, but it has since become
apparently that it suffers from scalability and maintenance issues.
It was deprecated in the Victoria cycle and can now be removed.
Hide the guide to upgrade to hardware types since it's very outdated.
I had to remove the iBMC diagram since my SVG-fu is not enough to fix it.
