Jitter requeue interval

[hiddeco]

To better distribute load when many resources have been configured with the same .spec.interval, we want to add +/-% jitter to the defined .spec.interval while requeuing the object after a successful reconciliation.

This behavior will be enabled by default with a value of 10 (between 4.5 and 5.5 minutes for an interval of 5m), but can be disabled or tweaked using the --interval-jitter-percentage flag on a controller.

• runtime: add jitter utils and options pkg#613
• controller: jitter requeue interval source-controller#1184
• kustomize-controller
• helm-controller

After more investigation, I do not think notification-controller, image-automation-controller and image-reflector-controller are good candidates for this. Because they are really lightweight during their reconciliation attempts, or have other means in place to regulate the pace at which things are reconciled (e.g. container registry scanning from the image-reflector-controller).

Let's remove those controllers from the list and close this issue as completed.
