    Description

      There is absolutely no need for NM to start ContainerManager on a standard port, it should bind to an ephemeral port. Binding on ephemeral ports will help us start multiple NMs on a single node without any issues.

      The same holds for the ResourceLocalizationService's server port and NM Http server's port.
