Add broken status to Product Intelligence metrics

What does this MR do?

After discussion on slack https://gitlab.slack.com/archives/CL3A7GFPF/p1621855171081600 ~"group::product intelligence" team decided to add new metric status broken that will be used to temporarily mark not working metrics until they got fixed or deprecated. Every metric marked with broken status should also have repair_issue_url attribute filled that appoints issue that defines corrective action
