Add a 'backends' tab to query details pages which shows: * host * total number of fragment instances for that query on that backend * number of still-running fragment instances * if the backend is complete (i.e. all instances finished) * peak memory consumption * the time, in ms, since a status report was received at the * coordinator from that backend. The table refreshes itself every second, controllable by a check-box. If the query has completed, no information is displayed. Testing: Add a new smoketest to test_web_pages.py.
