Clark Boylan 00348a4d0d Add tool to analyze check and gate success rates ...

This tool scans gerrit changes for comments from zuul over the last 30
days to build out success rates for check and gate pipelines. This only
looks at changes that have merged to avoid those that never can merge
because they only fail or are expected to fail.

  Changes: 4475
  Check Failures: 5317.0
  Check Successes: 9173.0
  Check Rate of failure: 0.3669427191166322
