IMPALA-12688: Support JSON profile imports for visualizing query timeline in 
webUI

A button has been added to import JSON query profiles for visualizing
them on the query timeline page.

The button opens a system dialog to browse only "*.json" files.

On selecting a valid query profile, the file is read through
JS FileReader APIs and parsed into a JSON for visualization on the
client's browser.

Previous utilization and fragment metrics charts are destroyed on
selecting a query profile.

Query ID and status on the page's header are also updated.
