gyfora opened a new pull request, #437:
URL: https://github.com/apache/flink-kubernetes-operator/pull/437
## What is the purpose of the change
Currently Flink 1.15+ application JMs are never shut down after termination.
This is not necessary as we only rely on them for one succesful observe step
from the operator logic perspective.
This PR introduces a configured time after which the operator shuts down
terminated application JMs. This allows users to still inspect the cluster for
some time but not have lingering pods forever.
## Brief change log
- *Add shutdown ttl config for application JMs*
- *Some FlinkService cleanup*
## Verifying this change
Extended the `ApplicationReconcilerTest` to cover for custom shutdown ttl.
