[jira] [Created] (AURORA-1472) TaskThrottle should have a configurable jitter

Stephan Erb created AURORA-1472:
-----------------------------------

             Summary: TaskThrottle should have a configurable jitter
                 Key: AURORA-1472
                 URL: https://issues.apache.org/jira/browse/AURORA-1472
             Project: Aurora
          Issue Type: Story
            Reporter: Stephan Erb


As an Aurora cluster operator, I need the ability to configure a random jitter which is added to the [throttle time of flapping jobs|https://github.com/apache/aurora/blob/06ddaadbcba4c66b8019815de6ca27d50a9df77d/src/main/java/org/apache/aurora/scheduler/scheduling/TaskThrottler.java#L73]. 

Background information: Due to some cascading failures, we ended in a state where many instances where throttled. Unfortunately, all these instances were restarted at the exact same time. This overloaded a backend used for package retrieval. A random jitter would have helped us to spread out the load on the backend service.
