Currently in domain mode a

/deployment-overlay=xxx:add(...)

results in a deployment overlay on ALL servers.

However for deployments

/deployment=xxx:add(...)

does not get pushed to the servers. This happens when it is associated with a server group:

/server-group=zzz/deployment=xxx:add(...)

Similarly

/deployment-overlay=xxx:add(...)

should not get pushed to the servers, until we have a

/server-group=zzz/deployment=yyy:add(...)

which picks out the servers we want to have the overlay
