Actually I looked a bit more at this and I don't think we want
kafka-clients or kafka itself to be marked as provided.
The `provided` scope tells the shade plugin or the assembly plugin when it
is creating the uber topology jar to not include this dependency in the uber
jar, because it will already be on the classpath. If we do this for the kafka
libraries any topology pom.xml will either have to explicitly include their own
version of kafka that is not `provided` or the topology jar will just not run.
Looking at storm-starter because of this it does not have kafka in the uber jar
so running any of the kafka examples will fail.
