    [SPARK-20355] Add per application spark version on the history server 
headerpage

    ## What changes were proposed in this pull request?
    
    Spark Version for a specific application is not displayed on the history 
page now. It should be nice to switch the spark version on the UI when we click 
on the specific application.
    Currently there seems to be way as SparkListenerLogStart records the 
application version. So, it should be trivial to listen to this event and 
provision this change on the UI.
    For Example

    {"Event":"SparkListenerLogStart","Spark Version":"2.0.0"}
    (Please fill in changes proposed in this fix)
    Modified the SparkUI for History server to listen to SparkLogListenerStart 
event and extract the version and print it.
    
    ## How was this patch tested?
    Manual testing of UI page. Attaching the UI screenshot changes here
    
    (Please explain how this patch was tested. E.g. unit tests, integration 
tests, manual tests)
