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.

This tool emits information like:

  Changes: 4475
  Check Failures: 5317.0
  Check Successes: 9173.0
  Check Rate of failure: 0.3669427191166322
  Gate Failures: 687.0
  Gate Successes: 4450.0
  Gate Rate of failure: 0.13373564337161767
  Total Failures: 6004.0
  Total Successes: 13623.0
  Total Rate of failure: 0.3059051306873185
