    [FLINK-2978][web-dashboard][webclient] Integrate web client into Web Frontend

    This PR creates an interface on the dashboard to perform the tasks the webclient is doing
right now, including displaying plans, submitting jobs and uploading jars.
    
    Here's a quick summary of changes:
    1. GET `/jars/list`: List of all available jars
    2. GET `/jars/:jarid/plan`: Plan for a job. Takes `entry-class`, `parallelism` and `program-args`
as query parameters.
    3. DELETE `/jars/:jarid`: Delete a jar.
    4. POST `/jars/upload`: Upload a new jar, limited to 10 MB size. 
    5. POST `/jars/:jarid/run`: Run a jar, and takes arguments just as in GET `/jars/:jarid/plan`.
    
    A new state is introduced on the dashboard, named `submit` which allows all these operations.
    
    Detailed screenshots:
    1. Overview page:

    2. Disabled mode [via config key `jobmanager.web.submit.allow`], for security purposes:
    
    ![disabled](https://cloud.githubusercontent.com/assets/8874261/11020610/65a29f46-864a-11e5-8fbf-c7d8c05e9803.png)
    
    3. Default state with no jars:
    
    ![no_jars_uploaded](https://cloud.githubusercontent.com/assets/8874261/11020613/71e0b824-864a-11e5-9b53-29d3325f0d65.png)
    
    4. Uploading a jar:
    
    ![uploading](https://cloud.githubusercontent.com/assets/8874261/11020616/7df20802-864a-11e5-8c4b-2fc1bd796e40.png)
    
    5. Arguments passing interface for the programs. This is shown only when a Jar has been
selected. At this point, the upload new button disappears, which can be brought back again
by unselecting.
    Entry classes can be loaded to the `entry-class` input box by clicking on the list items
under Entry Class.

    6. Plan, as a result of `Show Plan` button:
    
    ![plan](https://cloud.githubusercontent.com/assets/8874261/11020626/c8e172a8-864a-11e5-9c26-fa12e57edabc.png)
    
    7. Error reporting:
    Invalid entry class:

    Invalid parallelism:

    8. After clicking on submit, if the job was submitted successfully, it automatically redirects
to that job's page.

    10. Invalid file uploads:
    
    ![invalid_file_upload](https://cloud.githubusercontent.com/assets/8874261/11020641/447074dc-864b-11e5-907b-7fd80237ee7f.png)
    
    11. Disallow too large files:

    Of course, the best way to get the feel of it is to use it. :') Looking forward to comments
and suggestions.
