Clients can set an optional backoff time to the failed tasks

Is your feature request related to a problem? Please describe.
There is no way to have a job handler set the retry backoff time for a task. Therefore to achieve this functionality, one would need to handle it as part of the process. This is considered an anti pattern.

Describe the solution you'd like
Provide handlers with an API to fail jobs and set the retry backoff time. Similar to the merged solution for the Java client
