Alexandre Beslic ac6341066d Fix Consul Leader Election Failure on multi-server 
This fixes an error with Consul which fails to see a new
swarm leader after a consul leader soft restart because
of session renewal and missing status update.

Alexandre Beslic 5e8998eb6d Fix Consul Lock TTL with store failure 
If using the Lock TTL feature with Consul, the code
path in libkv is issuing a Put in the background through
the PeriodicRenewal call. The error is then eaten up and
ignored on the candidate loop. This would lead to the
candidate and followers being stuck in their candidate
loop. Consequence would be that they would not retry to
take the lock ending in a state with no Leader.

This patch restores an explicit error check instead of
wrongfully passing on the error to the channel before
giving it back to the caller.

Alexandre Beslic f21efa4337 Increase default TTL and heartbeat value 
Increases the default ttl and heartbeat value for discovery.
Because the node will still be listed for a long period on
`docker info`, there is now a Status to know if a node is
in the healthy or unhealthy state.

Daniel Hiltgen 3661b6e63b Add TLS support for libkv 
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
        --advertise 192.168.122.47:3376
        etcd://192.168.122.47:2379
