[SURE-9061] Jobs are not cleaned up from local cluster

[mikmatko]

Is there an existing issue for this?

Current Behavior

In Rancher local cluster, for each commit/change in each GitRepo, there is a Job started by Fleet. There is nothing to clean up these Jobs, so you will quickly end up with hundreds of lingering Job objects and their completed Pods.

I didn't notice this behavior in Fleet 0.9.x, so I assume something in 0.10.x introduced these Jobs. I was assuming this is related to automatic chart dependency update, but setting disableDependencyUpdate to true doesn't seem to affect.

Expected Behavior

Unnecessary Job objects are cleaned up, e.g. by setting some sane default for .spec.ttlSecondsAfterFinished: https://kubernetes.io/docs/concepts/workloads/controllers/ttlafterfinished/

Steps To Reproduce

1. Install Rancher & Fleet
2. Add any GitRepo and make sure it deploys
3. Check rancher-local cluster. You now have lingering Job objects

Environment

- Fleet Version: v0.10.2
- Cluster:
