Sebastiaan van Stijn 81eef17e38 Return a warning when running in a two-manager setup ...

Running a cluster in a two-manager configuration effectively *doubles*
the chance of loosing control over the cluster (compared to running
in a single-manager setup). Users may have the assumption that having
two managers provides fault tolerance, so it's best to warn them if
they're using this configuration.

This patch adds a warning to the `info` response if Swarm is configured
with two managers:

    WARNING: Running Swarm in a two-manager configuration. This configuration provides
             no fault tolerance, and poses a high risk to loose control over the cluster.
             Refer to https://docs.docker.com/engine/swarm/admin_guide/ to configure the
             Swarm for fault-tolerance.
