gyfora opened a new pull request, #631:
URL: https://github.com/apache/flink-kubernetes-operator/pull/631
## What is the purpose of the change
The main goal is to support setting default configuration on a per-namespace
and per-flink version level.
This would allow us for example to set config defaults differently for Flink
1.18 (enable adaptive scheduler by default)
Or to use different reconciliation/operator settings for different
namespaces.
Syntax:
```yaml
# Version Specific Defaults
kubernetes.operator.default-configuration.flink-version.v1_17.key: value
# Namespace Specific Defaults
kubernetes.operator.default-configuration.namespace.ns1.key: value
```
Flink version specific defaults will have a higher precedence so namespace
defaults would be overridden by the same key.
## Brief change log
- *Add logic to FlinkConfigManager*
- *Rework config access through resource context*
- *Add unit tests*
## Verifying this change
