---------------------------------------

Thanks for creating this ticket [~Fil Karnicki]. I like this idea. Could environment variables be another mechanism to supply placeholder values?

> Add the ability for users to provide placeholders in module.yaml, e.g.
> {code:java}
> kind: com.foo.bar/test
> spec:
>   something: ${REPLACE_ME}
>   transport:
>     password: ${REPLACE_ME_WITH_A_SECRET}
>     array:
>       - ${REPLACE_ME}
>       - sthElse {code}
> These placeholders would be resolved in 
> org.apache.flink.statefun.flink.core.jsonmodule.RemoteModule#bindComponent
> using 
> {code:java}
> ParameterTool.fromSystemProperties().mergeWith(ParameterTool.fromMap(globalConfiguration) {code}
> by traversing the ComponentJsonObject.specJsonNode() and replacing values that contain placeholders with values from the combined system+globalConfig map
