    [FLINK-1501] Add metrics library for monitoring TaskManagers

    Hey,
    I've spend some time exploring the [metrics](https://dropwizard.github.io/metrics/3.1.0/) library for improving the performance monitoring in Flink.
    
    This pull request is a first step into that direction. The primary objective is a clean integration of the JVM monitoring into our system.
    
    I spend probably 80% of the time in making the javascript frontend work. For that, I've used [rickshaw](https://github.com/shutterstock/rickshaw), a project also used by projects like Apache Ambari for creating nice graphs.
    Still, the visualization is not perfect and I would like to see incremental improvements there.
    
    The next step for me will be metrics for individual jobs.
