[JENKINS-37908] docker 1.12 swarm support for docker-plugin

Does the Docker Plugin support connecting a Swarm using docker engine 1.12+ ?

I cannot connect to the swarm as a new "Cloud" and am seeing this error:Caused by: shaded.org.apache.http.ProtocolException: The server failed to respond with a valid HTTP response

I could successfully connect Swarm using docker engine 1.10:

Version = swarm/1.2.4
