Persistent failure report

[drsm79]

Overview

It would be good to have a report that highlights persistent failures - checks that consistently fail for many days.

Requirements

• configurable threshold for persistent failure, measured in time
• report is a list of check, time period of failure pairs & last successful run (check foo has been failing for 8 days, last successful run $TIMESTAMP)
• if we were clever, could extend to flapping tests...

Approach

Test Plan

Will need some fake result data to demonstrate persistent failure.
