Post Upgrade / Post Install Job TTL

[dakaneye]

What would you like to be added?

The ability to configure the jobs:

• redpanda-configuration
• redpanda-post-upgrade

with a Job.spec.ttlSecondsAfterFinished (see kubectl explain job.spec)

Why is this needed?

The standard redpanda installation comes with two jobs that help for post upgrade and configuration: i.e.:

redpanda-configuration                      1/1           5s         12h
redpanda-post-upgrade                       1/1           5s         12h

They leave completed pods in the namespace it's installed in for a lot longer than they need to be there. I think we could add a configuration option to allow for a TTL to be set (defaulting to the current behavior) so that the pods can optionally get cleaned up after the jobs run

Pods left unused can tie up node resources: i.e. ports or tie up cpu/mem via resources.request
