    [SPARK-4145] [WIP] Web UI job pages

    This PR adds two new pages to the Spark Web UI:
    
    - A jobs overview page, which shows details on running / completed / failed 
jobs.
    - A job details page, which displays information on an individual job's 
stages.
    
    The jobs overview page is now the default UI homepage; the old homepage is 
still accessible at /stages.
    
    In some situations, the jobs page may display "No information on stage" for 
some stages of pending jobs that have not begun executing.  This is due to some 
limitations in how JobProgressListener finds out about stages.  We can address 
this later as part of a separate scheduler PR.

    #### Job details page
    
    (This is effectively a per-job version of the stages page that can be 
extended later with other things, such as DAG visualizations)

    Rename JobProgressPage to AllStagesPage:
    
    This will avoid confusion once we have a page that lists all jobs.
