Subject: [PATCH] [test only] add "Create Heavy Load" button to node page

This will set up a timer which updates the node hostname every 200 msec, to
simulate high load for testing frontend performance in browsers.

The notification box for successful updates has been disable for this test
since it would fill the screen otherwise.
