Description

Hi

I see there's a missalingment between the features dependencies and the pom of the camel-kafka component that makes impossible to run a Producer in karaf. I can see that in the features.xml

<bundle dependency='true'>mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.kafka-clients/${kafka-clients-bundle-version}</bundle>
    <bundle dependency='true'>mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.kafka_2.10/${kafka-bundle-version}</bundle>

It's trying to use 2.10 scala version, but in the pom.xml we point to 2.11 scala version

 <dependency>
      <groupId>org.apache.kafka</groupId>
      <artifactId>kafka_2.11</artifactId>
      <version>${kafka-version}</version>
      <exclusions>
        <exclusion>
          <groupId>org.slf4j</groupId>
          <artifactId>slf4j-simple</artifactId>
        </exclusion>
          <exclusion>
              <artifactId>scala-library</artifactId>
              <groupId>org.scala-lang</groupId>
          </exclusion>
      </exclusions>
    </dependency>

this causes some Class not found exceptions (funny some how) only in the producer, but the consumer is ok.

org.apache.camel.FailedToCreateProducerException: Failed to create Producer for endpoint: Endpoint[kafka://.........].
Reason: java.lang.ClassNotFoundException: kafka.serializer.DefaultEncoder

I see this is already fix in master... so this should not apply to 2.17.0
