This adds TLS support into the KV store for swarm. The manage, join,
and list commands all have a new CLI argument, matching the docker engine
discovery backend. This required adding the tlsconfig utility
package from docker engine.
Here's an example showing re-use of the cluster certs for the KV store:
swarm manage --tlsverify \
--tlscacert /etc/docker/ssl/ca.pem
--tlscert /etc/docker/ssl/cert.pem
--tlskey /etc/docker/ssl/key.pem
--discovery-opt kv.cacertfile=/etc/docker/ssl/ca.pem
--discovery-opt kv.certfile=/etc/docker/ssl/cert.pem
--discovery-opt kv.keyfile=/etc/docker/ssl/key.pem
