[cdwg] Monitoring Ticket Progress

[Christopher J. Morrone]

Folks asked on last CDWG for some clarification about the issues that I 
noted with the proposed gerrit filters.  Here are some details.

Lets start with the following filter, which is intended to show all 
patches that have not yet completed the review process.

 
http://review.whamcloud.com/#/q/status:open+age:1mon+Verified%252B1+-Verified-1+-CodeReview-1+-CodeReview-2,n,z

We can ignore that it isn't also filtering out other projects and 
branches other than master.  Those are easily fixable.  But there are 
problems that are less easily fixed.

For instance, it returns this ticket:

   http://review.whamcloud.com/#/c/6520/

At the time of writing this email, that has two +1 CodeReviews, and has 
been sent to the "Gerrit Gatekeeper" for landing.  That patch is should 
not appear in the "waiting for reviews list".  Instead it should be on 
the "reviewed, but not landed" list.

But conversely, the "reviewed but not landed" filter is this:

http://review.whamcloud.com/#/q/status:open+age:1mon+Verified%252B1+CodeReview%252B2+-Verified-1+-CodeReview-1+-CodeReview-2,n,z

and the mentioned ticket does _not_ appear on that list.  That filter 
is, in fact, grossly under reporting the number of patches that are 
fully reviewed and waiting to land.  It only shows the patches that have 
gotten a +2 CodeReview, which is only a subset of the patches that are 
reviewed and waiting to land.
