I am using the following Deployer Property for SCDF to give my Stream Source a label.

deployer.my-source.kubernetes.deploymentLabels=importer-source:myimporter

The thing is that I have to manually write this down for every redeployment I want to do with this stream. I was seeing a Skipper Configuration that has all the properties that are visible in the SCDF Streams Deployer Properties. But I was not able to find the deploymentLabel property in there. I think its some kind of custom property? As you can see it is not listed in here: https://dataflow.spring.io/docs/feature-guides/streams/deployment-properties/

But it does work so I wonder how I can set it in skipper since it's no "official" or documented property.
