IMPALA-11970: Optimized rendering for the query timeline display
Decoupled the retrieval of attributes and rendering
to optimize window resize events for large JSON
query profiles in the timeline display.
A reload will be triggered after every second,
in case the query execution has not completed,
or due to errors in parsing the profile;
only valid profiles are rendered.
Replaces 'maximum()' and 'minimum()' functions with
'Math.max.apply()' and 'Math.min.apply()'.

> Query profiles contain timing information for fragments and plan nodes that
> is difficult to analyze in a text format, especially for complex and
> highly-parallel execution plans. A graphical display in the WebUI that
> renders timing information in Gantt chart form will make the execution timing
> and dependencies much easier to follow.
