This changes `docker swarm help` to be consistent with capitals and removes full stops. Before: ``` Commands: init Initialize a Swarm. join Join a Swarm as a node and/or manager. update update the Swarm. leave Leave a Swarm. inspect Inspect the Swarm ``` After: ``` Commands: init Initialize a Swarm join Join a Swarm as a node and/or manager update Update the Swarm leave Leave a Swarm inspect Inspect the Swarm ``` Signed-off-by: Anil Madhavapeddy <anil@docker.com> Upstream-commit: 0ec78739ac7d8ec1579d1d4fd63cd207dc56e7c8 Component: engine
