> 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.
