During last couple weeks there is an increasing demand on tracking
3rd-party CI statuses. We at Stackalytics decided to be in trend and (with
some inspiration from Salvatore's proposal) implemented report that shows
summary on external CI status. The initial version is available for Neutron
- http://stackalytics.com/report/ci/neutron/7

The report shows summary of all CI jobs during specified period of time,
 * stats of runs on merged patch sets:
    - total number of runs
    - success rate (success to total ratio)
    - time of the latest run
    - last test result
  * stats for all patch sets (the same set as for merged)
  * last test results for every merged patch set grouped by days (useful to
see how different CIs correlate with each other and how often they run)

Under "merged patch set" report means "the last patch set in the merged
change request", thus it is almost the same as the trunk code. CI
configuration is taken from DriverLog's default data
Standard Stackalytics screen is also available for CIs -
http://stackalytics.com/?metric=ci, including votes breakdown and activity

Since this is the first version there are some open questions:
 * Currently report shows results per CI id, but there are CIs that run
tests against multiple drivers and this case is not supported. What would
be more useful: to get stats for a driver or for CI?
 * Most CIs run tests when patch set is posted. So even if change request
is merged within selected time period corresponding CI results may be
 * Patterns for non-voting CIs need to be verified. For example Cisco CI
now runs 5 jobs, but DriverLog data still contains old data.
