Add ability to specify maximum replicas per node

[kiska3]

Currently in CLI on the docker swarm manager I am performing:
docker service create --mode replicated --replicas 200 --replicas-max-per-node 4 --name <name> <insert registry>

There is no way of specifying in the UI maximum replicas per node.
My workaround this issue is to create the service in the UI, then execute in CLI docker service update --replicas-max-per-node 2 <name>

I would like to be able to do all that in one step from the UI instead of logging into the manager to do it
