gyfora opened a new pull request, #551:
URL: https://github.com/apache/flink-kubernetes-operator/pull/551
## What is the purpose of the change
Currently we use the default (background) deletion propagation when we
delete Kubernetes resources such as the JobManager deployment.
In most cases this is acceptable however this can lead to lingering
resources when the garbage collection is slow on the k8s cluster. We therefore
propose to make this configurable and also change the default to Foreground
which is more predictable and works better for our purposes in the operator.
## Brief change log
- *Change default resource deletion to foreground propagation*
- *Make it configurable*
- *Add tests*
