Allow setting ttlSecondsAfterFinished on the init job

[RegisHubelia]

When using mechanism like rancher fleet - ttlSecondsAfterFinished set to 300 forces an update as the job is being deleted after 5 minutes. The Init job is then recreated every 5-6 minutes. It would be great if we can set that value (in my case null) in the chart as it is currently hardcoded to 300. A combination of this with randomName would fix the resync loop issue.
