CI/CD analytics now shows accurate pipeline rates

In previous versions of GitLab, the failure rate and success rate metrics on the CI/CD analytics page (<project>/-/pipelines/charts) included canceled and skipped pipelines in their calculations. This caused both rates to appear lower than expected. For example, on gitlab-org/gitlab the two rates summed to only 98% instead of approximately 100%.

Now, GitLab calculates the failure rate and success rate using only completed pipelines, so the results accurately reflect your pipeline health.
