Directly instrumented applications use a Prometheus client library that
follows our guidelines, and can be used as examples of software doing
that.

Recategorise things accordingly, updating links as needed and
adding some more I know of.

as it's commercial software and thus I can't check.
kubernetes-mesos has no instrumentation that I can find.

Make absolute links relative in docs

Kumina a company based in the Netherlands doing managed operations for
Linux-based systems. Kumina has switched over to Prometheus over the
last year and is now using it as its exclusive monitoring system for
some of its customers.

In the process, Kumina has developed (and is still developing) metrics
exporters for many pieces of commonly used Open Source software. Most of
these can be found on our company's GitHub page:

Kumina is promoting the use of Prometheus and affiliated projects, like
Kubernetes, by giving talks about them at Open Source conferences in the
Netherlands.

While the document refers to JMX for Kafka monitoring, unfortunately JMX doesn't expose consumer group stats.

I was told that it was OK to directly sending a PR for this. Please, let me know if it is not.
