Description

In order to support Knox proxying of the debug webui, we should fully qualify all links on our debug web ui with the host:port.

This will allow us to create rewrite rules that do the transform:
<a href="host:port/path">...</a>
=>
<a href="<knox-host>/topology/impalaui/path?host=host&port=port>...</a>

One complication is preventing regressions when future links are added, since this is a difficult thing to test for
