Add ConsecutiveFailureLimit to AnalysisTemplate/ClusterAnalysisTemplate

# Summary

Analysis templates currently support passing the analysis after N consecutive successes and/or failing after N total failures.

We'd love the ability to fail after N consecutive failures as well.

# Use Cases

This would be used to minimize "false positive" rollbacks, in cases where the metric that underlies the analysis may be slightly flaky. Requiring consecutive failures would give more confidence that something was actually wrong, rather than the system responding to a blip.

Need this enhancement? Give it a 👍. We prioritize the issues with the most 👍.

Start by locating the AnalysisTemplate and ClusterAnalysisTemplate definitions and the existing consecutive-success and total-failure handling. Add the requested consecutive-failure limit to both template types, then verify that tests cover failing only after the configured number of consecutive failures.
