    [SPARK-13275] [Web UI] Visually clarified executors start time in timeline

    ## What changes were proposed in this pull request?
    Updated the Executors added/removed bubble in the time line so it's clearer 
where it starts. Now the bubble is left justified on the start time (still also 
denoted by the line) rather than center justified.
    ## How was this patch tested?
    Manually tested UI
