[jira] [Created] (FLINK-26570) Remote module configuration interpolation

Fil Karnicki created FLINK-26570:
------------------------------------

             Summary: Remote module configuration interpolation
                 Key: FLINK-26570
                 URL: https://issues.apache.org/jira/browse/FLINK-26570
             Project: Flink
          Issue Type: Improvement
          Components: Stateful Functions
            Reporter: Fil Karnicki


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
