The system to add zuul status to gerrit pages is very inefficient and is causing high load on the zuul server as well as poor performance in browsers. Remove it until it can be reworked to be more efficient. This reverts commit 5be687279c6a5284a39e1e62e928b5cf5b359aa3. This reverts commit 0118d2b4b53cea2641c123a57c14bf8276237f09.
