docs: replace threshold with thresholdRange

docs/gitbook/dev/upgrade-guide.md

@@ -23,3 +23,19 @@ Upgrade procedure:
 **Note** that after upgrading Flagger, all canaries will be triggered as the hash value used for tracking changes
 is computed differently. You can set `spec.skipAnalysis: true` in all canary manifests before upgrading Flagger,
 do the upgrade, wait for Flagger to finish the no-op promotions and finally set `skipAnalysis` to `false`.

+Update builtin metrics:
+* replace `threshold` with `thresholdRange.min` for request-success-rate
+* replace `threshold` with `thresholdRange.max` for request-duration
