Issue:
I am trying to do a REST API call to create a electricflow job execution. When I run that REST call it will respond with a json of the ID for that execution and I want to parse that ID into a groovy variable

Steps to resolve:
From what I am seeing the `perform` method here: https://github.com/jenkinsci/electricflow-plugin/blob/master/src/main/java/org/jenkinsci/plugins/electricflow/ElectricFlowGenericRestApi.java#L68 does not return a value into a groovy variable. In my opinion it should be like `ReturnStdOut` on a shell step inside of a pipeline rather than just printing into the logs. This would allow other REST calls to check on the status the build using the ID which is returned
