    [FLINK-1984] Integrate Flink with Apache Mesos

    This pull requests adds a mesos scheduler and an executor (inspired from the work done
in, now abandoned, PR #251). The highlights are as follows:
    
    * The mesos scheduler is starts a jobManager in a parallel thread based on the configuration
provided using `--configDir` argument.
    * The mesos scheduler is not HA and should be used with marathon or similar service to
ensure that there is always one instance running. This may be addressed in future patches.
    * The mesos scheduler uses the some new properties which can be set using the `conf/flink-conf.yaml`.
The configuration directory can be specified using the `--confDir` command line argument and
a list of configuration values is present in `flink-mesos/src/main/scala/org/apache/flink/mesos/scheduler/package.scala`.
    
    Example usage:
    
    ```bash
    mvn clean package -DskipTests -Pinclude-mesos
    java -Dlog4j.configuration=file:/vagrant/log4j.properties -cp *.jar org.apache.flink.mesos.scheduler.FlinkScheduler
--conf-dir /vagrant
    ```
    
    ```yaml
    # flink-conf.yaml
    
    flink.mesos.master: zk://127.0.0.1:2181/mesos
    flink.uberjar.location: file:///vagrant/flink-dist-0.10-SNAPSHOT.jar
    flink.mesos.taskmanagers.mem: 512
    flink.mesos.taskmanagers.cpu: 0.5
    taskmanager.logging.level: INFO
    streamingMode: streaming
    
    jobmanager.web.port: 8081
    webclient.port: 8080
    ```
    
    ```
    # log4j.properties
    
    log4j.rootLogger=INFO, console
    
    log4j.appender.console=org.apache.log4j.ConsoleAppender
    log4j.appender.console.layout=org.apache.log4j.PatternLayout
    log4j.appender.console.layout.ConversionPattern=%-5p %d{ISO8601} [%t] %c{1}: %m%n
    
    # suppress the warning that hadoop native libraries are not loaded (irrelevant for the
client)
    log4j.logger.org.apache.hadoop.util.NativeCodeLoader=OFF
    log4j.logger.org.apache.flink.mesos=DEBUG
    
    # suppress the irrelevant (wrong) warnings from the netty channel handler
    log4j.logger.org.jboss.netty.channel.DefaultChannelPipeline=ERROR, console
    
    ```
    
    An easy way to test this is using https://github.com/mesosphere/playa-mesos to start a
mesos cluster in virtualbox (using vagrant) and copying the uberjar to /vagrant and running
the above command. The job manager web UI url is set as the mesos framework url.
