The kubeadm survey for 1.13:
https://docs.google.com/forms/d/1A855D054FZfdvNbx6mAa54tcZ204GmPCIhxe1UrXKd8/edit#responses

Revealed the top 3 plugins in terms of popularity are:

Flannel
Calico
WeaveNet
The kubeadm maintainers are in contact with the maintainers
of these plugins and can provide support and updates to this guide.

The rest of the plugins in the guide are unmaintained, by the kubeadm team!

Some plugins are not in the CNCF landscape, or maintained by the kubeadm team, but still
present in the guide.

Remove the following non-CNCF / unmaintained plugins:

AWS VPC
Romana
Juniper*
Canal (it is an alternative to Calico and already explained in the
Calico guide)
Add note that users can still defer to this page for more options and a more complete list:

Jan-Philip Gehrcke f6c402a2bd jobs: clarify that there is no restartPolicy for the job itself (#18605)
Sometimes, as it happened to me, a Pod's `restartPolicy` 
is mistakenly taken as the corresponding Job's restart policy.

That was concluded before, here:
https://github.com/kubernetes/community/pull/583/files

The confusion happened here:
https://github.com/kubernetes/kubernetes/issues/30243
https://github.com/kubernetes/kubernetes/issues/43964

And here:
https://github.com/jaegertracing/jaeger-kubernetes/issues/32

This commit tries to clarify that there is no `restartPolicy` for
the job itself, and that using either of `backoffLimit` and
`activeDeadlineSeconds` may result in permanent failure.

Antonio Ojea d2dc2c60c6 Use dnsutils image for DNS debugging (#18001)
DNS debugging documentation is using a busybox image as example.
This image has different known issues with the way it resolves
the DNS names in k8s, creating confusion with users that try to
follow the docs.

The e2e tests use a custom small image ~4.3MB for DNS testing
with all the necessary tools. Also, the fact that this image is
being used for the k8s e2e testing guarantees it's compatibility.

tom1299 93eae7bf31 Improve wording of “Connecting Applications with Services” (#18076)
* Exchanged developers with containers

The meaning of original sentence: "Coordinating ports across multiple **developers** is very difficult to do at scale..." is not really obvious. From what I understand from the context of this page, the term **containers** would make more sense, because the context in this paragraph is on containers and ports rather than developers.

* Clarify terms developer and container

Rephrased statement on port coordination to make
it claerer that the ports are part of the
containers provided by developers or teams.

* Update content/en/docs/concepts/services-networking/connect-applications-service.md
