    [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:

    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:

    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:

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

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