      Description

      RMStateStore stores enough information to recover applications in case of a restart. The store also retains this information for completed applications to serve their status to REST, WebUI, Java and CLI clients. We don't need all the information we store today to serve application status; for instance, we don't need the ApplicationSubmissionContext.
