    [FLINK-7991][examples][kafka] Cleanup kafka10 example jar

    ## What is the purpose of the change
    This PR cleans up the kafka example shading configuration, removing plenty of unnecessary
classes from the resulting jar along with several ineffective inclusions.
    ## Brief change log
    * remove inclusions for zk, curator, jute, I0Itex, jline and jammer as they are ineffective
    * narrow down `org.apache.flink.streaming` inclusion to only include the kafka connector
    ## Verifying this change
    * Build jar before and after and compare contents

>                 URL: https://issues.apache.org/jira/browse/FLINK-7991
>             Project: Flink
>          Issue Type: Bug
>          Components: Examples
>    Affects Versions: 1.4.0, 1.5.0
>            Reporter: Chesnay Schepler
>            Assignee: Chesnay Schepler
>             Fix For: 1.4.0, 1.5.0
> The kafka example jar shading configuration includes the following files:
> {code}
> <include>org/apache/flink/streaming/examples/kafka/**</include>
> <include>org/apache/flink/streaming/**</include>
> <include>org/apache/kafka/**</include>
> <include>org/apache/curator/**</include>
> <include>org/apache/zookeeper/**</include>
> <include>org/apache/jute/**</include>
> <include>org/I0Itec/**</include>
> <include>jline/**</include>
> <include>com/yammer/**</include>
> <include>kafka/**</include>
> {code}
> Problems:
> * the inclusion of org.apache.flink.streaming causes large parts of the API (and runtime...)
to be included in the jar, along the _Twitter_ source and *all* other examples
> * the yammer, jline, l0ltec, jute, zookeeper and curator inclusions are ineffective;
none of these classes show up in the example jar
