James E. Blair ff6d73b989 Revert zuul status in gerrit
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.

* This function takes the full list of comments, the current patch
* number, and builds an array of (pipelinename, comments array)
* tuples. That makes it very easy to process during the display
* phase to ensure we only display the latest result for every

*
* Comments that do not have a parsable pipeline (3rd party ci
* systems) get collapsed by name, and we specify 'check' for their
* pipeline.
