This would be limited to creating or removing a cache using an existing 
configuration template. Example:

I have a cluster of two standalone nodes A and B with a cache X running.
A client requests the creation of a cache Y and both A and B add that.
Node C which joins the cluster later will also need to start cache X.

You are probably going to tell me that this is something Domain 
management should do, or some external configuration provisioning system 
(e.g. Ansible). I'm exploring the various possibilities here to see what 
can be done.
