Reduce size of software-configs in user-data

[Spyros Trigazis]

In a default nova deployment user-data for software deployments
goes into nova's db. That field is 64KB, so we are contraint by
space and we need to pass only what is needed.

In our case at CERN, were we have some *small* custom software-configs
exceeded that limit. Upstream we are really close: at 63880 bytes.

We need to investigate further how to reduce that size. Even from a performance
perspective. Writing and Reading 60KB in nova's db is not a very good practice.

For starters we can remove the absolutely redundant kube-examples (3.3KB). We could add them somewhere in our docs.

    software-configurations:
    * prometheus-monitoring
    ** pin prometheus to v1.8.2 since its config is not 2.0.0
