Allow applying the same configuration changes to multiple Standalone nodes

I would like to request a supporting configuration changes to multiple standalone nodes the same way as currently DMR in domain mode works.

The main motivation behind that is using WF based Projects (like Infinispan HotRod Server) in the Cloud. By using DMR we can ensure changing configuration on the fly, which is very important in our case.

In Infinispan project we use DMR to propagate configuration changes to all nodes in the cluster (e.g. adding a cache, changing it etc). When considering Cloud deployment we use Standalone mode. It would be nice to find a way to propagate configuration changes to all servers the same way as we do in Domain mode.
