Removes some "platform" ideas from readme as they need real PRs

rather than a couple of sentences. In response to #103.

Regarding Kafka Streams I no longer think we need examples,
because any dockerized streams application can run as a deployment.

An example of Kafka Connect would be useful, in particular
the combination of a custom image (or one with stock connectors)
and a Connect cluster manifest.
This is tracked in #69, but not the relation to
https://github.com/solsson/dockerfiles/tree/master/connect-*

KSQL (#68) is highly interesting.

 That's it. Just add business value :wink:.
-For clients we tend to use [librdkafka](https://github.com/edenhill/librdkafka)-based drivers like [node-rdkafka](https://github.com/Blizzard/node-rdkafka).
-To use [Kafka Connect](http://kafka.apache.org/documentation/#connect) and [Kafka Streams](http://kafka.apache.org/documentation/streams/) you may want to take a look at our [sample](https://github.com/solsson/dockerfiles/tree/master/connect-files) [Dockerfile](https://github.com/solsson/dockerfiles/tree/master/streams-logfilter)s.
