   There seems to be three different versions of netty originally
   
   ```
   $ git checkout release-1.1.0-rc2
   $ mvn clean -DskipTests package -Pdist
   $ jar -tf webapp/target/atlas-webapp-1.1.0.war | grep netty
   WEB-INF/lib/netty-buffer-4.0.37.Final.jar
   WEB-INF/lib/netty-handler-4.0.37.Final.jar
   WEB-INF/lib/netty-3.7.0.Final.jar
   WEB-INF/lib/netty-common-4.0.37.Final.jar
   WEB-INF/lib/netty-transport-4.0.37.Final.jar
   WEB-INF/lib/netty-codec-4.0.37.Final.jar
   WEB-INF/lib/netty-all-4.0.23.Final.jar
   ```
   
   ## After applying the fix in this PR, it goes down to two
   ```
   $ jar -tf webapp/target/atlas-webapp-1.1.0.war | grep netty
   WEB-INF/lib/netty-3.7.0.Final.jar
   WEB-INF/lib/netty-all-4.0.23.Final.jar
   ```
   
   Zookeeper seems to be pulling the 3.7.0 version. I excluded it from ./pom.xml  (it becomes:
   ```
   <dependency>
       <groupId>org.apache.zookeeper</groupId>
       <artifactId>zookeeper</artifactId>
       <version>${zookeeper.version}</version>
       <exclusions>
           <exclusion>
               <groupId>io.netty</groupId>
               <artifactId>netty</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   ```
   )
   
   After that, seeing only one version of netty
   ```
   jar -tf webapp/target/atlas-webapp-1.1.0.war | grep netty
   WEB-INF/lib/netty-all-4.0.23.Final.jar
   ```
