IMPALA-9866: Query plan debug page stuck in fetch and render loop.

Once a query is completed we stop fetching and rendering the plan. This
speeds interaction with large query plans in the web browser as well as
reduces some load on the query coordinator.

> The query plan debug page fetches and re-renders the query plan graph every second event after the query has completed.
>  
> For large query plans this makes interacting with the graph much slower and resource intensive on the user's web browser. Also it put a strain on the coordinator node as large query plans can be several megabytes in size and is constantly re-transmitted while the user has the query plan page open.
