Make maven build independent of missing dependencies

[siom79]

After having cloned the project from git, the build fails because it cannot resolve some transitive dependencies from zookeeper and the used maven-thrift-plugin is not available on the central repository.

Add the following exclusions for the missing jmx and jms libraries to pom.xml for chorons-client:

    <dependency>
      <groupId>org.apache.zookeeper</groupId>
      <artifactId>zookeeper</artifactId>
      <version>3.4.4</version>
        <exclusions>
            <exclusion>
                <groupId>com.sun.jmx</groupId>
                <artifactId>jmxri</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.sun.jdmk</groupId>
                <artifactId>jmxtools</artifactId>
            </exclusion>
            <exclusion>
                <groupId>javax.jms</groupId>
                <artifactId>jms</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

and upgrade maven thrift plugin to 0.1.11:

      <plugin>
        <groupId>org.apache.thrift.tools</groupId>
        <artifactId>maven-thrift-plugin</artifactId>
        <version>0.1.11</version>
        ...
      </plugin>
