[WIP] Updates daemonset for Kube 1.16, also docs and adds pre-1.16 daemonset

[dougbtv]

A few issues here...

@s1061123 -- Tomo these changes you made look great! Thank you so much for fixing this up. This looks great by me, we can merge it at will.

Edit to add: Tested it on my local cluster and it works flawlessly.

CNI Version also needs to get added to cni-conf.json, otherwise it fails when customizing it
