If you have a look at CloudControllerServiceImpl startContainers method,
MemberContext's properties contain the payload parameters. Those parameters
eventually passed as environment variables to the container, you can find
that logic in
org.apache.stratos.cloud.controller.functions.MemberContextToKubernetesContainer
apply method.
