Title: Fix StartableMethods.stopSequentially

- need to mark sub-tasks as inessential; otherwise failure of one will cause all subsequent tasks not to be executed!

Was causing problems in `ContolledDynamicWebAppCluster`, such as in `WebClusterDatabaseExampleApp` - if nginx failed to stop for any reason then it meant we didn't stop the app-servers in the cluster.
