Remove the id field to fix this error:
```
$ kubectl create -f redis-slave-controller.json
error validating "redis-slave-controller.json": error validating data: found invalid field id for v1.ReplicationController; if you choose to ignore these errors, turn validation off with --validate=false
```
Fixes#17846
hypothesis: The old userspace proxier would internally retry connections. The
new one does not. When this test comes up, the firewall might not yet be open or
something is causing a long delay and a timeout. I can't repro this failure
locally, so I am shooting in the dark. It's sort of plausible.
evidence: I can SSH into the jenkins master that is hung and I can see the hung
curl. I can run that curl by hand and it works. I can see that my shell is in
the same netns as that hung curl.
Introduce examples explaining how to use DataSets to optimally
distribute cassandra nodes onto each kubernetes node in the network.

This adds a very basic Zeppelin image that works with the existing
Spark example. As can be seen from the documentation, it has a couple
of warts:
* It requires kubectl port-forward (which is unstable across long
periods of time, at least for me, on this app, bug incoming). See
* I needed to roll my own container (none of the existing containers
exactly matched needs, or even built anymore against modern Zeppelin
master, and the rest of the example is Spark 1.5).
The image itself is *huge*. One of the further refinements we need to
look at is how to possibly strip the Maven build for this container
down to just the interpreters we care about, because the deps here
are frankly ridiculous.
This might be a case where, if possible, we might want to open an
upstream request to build things dynamically, then use something like
probably the cut the image down considerably. (This might already be
possible, need to poke at whether you can late-bind interpreters
later.)
Adds an example using DaemonSets to distribute the NewRelic worker onto all nodes in a k8s cluster.
