Change `docker service update` to replace attributes of the target
service rather than augment them. One particular occurrence where the
previous behavior proved problematic is when trying to update a port
mapping: the merge semantics provided no way of removing published
ports, but strictly of adding more.
The utility merge* functions where renamed accordingly to update*.

As described in our ROADMAP.md, introduce new Swarm management commands
to call to the corresponding API endpoints.
This PR is fully backward compatible (joining a Swarm is an optional
feature of the Engine, and existing commands are not impacted).
