    [FLINK-1579] [WIP] Implement Standalone HistoryServer

    This PR is a work-in-progress view over a standalone History Server (HS).
    
    JobManagers may send completed jobs to the HistoryServer for them to be 
archived. Upon receiving an ArchivedExecutionGraph the HS pre-computes all 
possible REST requests and writes them into files. The files are arranged in a 
directory structure corresponding to the REST API.
    
    The HS can be started by calling `./bin/historyserver.sh start`, similar to 
the JM/TM. Various config options exist for the HS that mostly mirror the 
web-ui/RPC options of the JM.
    
    The HS uses a slightly modified web-ui; basically it only shows the 
"Completed Jobs" page. To not duplicate the everything I've added 2 files, 
`index2.jade` and `index2.coffee`, to the build script. The resulting 
`index2.html` file will be loaded when the browser requests the `index.html`.
    
    In order to re-use the JSON generation code that previously was contained 
in various handlers a giant utility `JsonUtils` class was created. This class 
now contains a variety of static methods that generate the JSON responses. As a 
result most handlers were reduced to one-liners, bar some sanity-checks.
    
    In regard to tests we verify that the HS creates all expected files upon 
receiving an ExecutionGraph.
    Furthermore, the newly created JsonUtils are mostly tested (the new 
checkpoint stats aren't tested); so we have tests for the REST responses now, 
which is neat.
    
    I'm not opening a proper PR yet as i have to go through all changes once 
again in detail, but it works (locally and on a cluster) so i wanted people to 
try it out and get some feedback.

> Right now its not possible to analyze the job results for jobs that ran on 
> YARN, because we'll loose the information once the JobManager has stopped.
> Therefore, I propose to implement a "Flink History Server" which serves  the 
> results from these jobs.
> I haven't started thinking about the implementation, but I suspect it 
> involves some JSON files stored in HDFS :)
