7cf2d7f1d8 Support Zodiac-based deployments
Since Zodiac always uses image IDs for deployments we can relay on the
standard container image field to determine the image that was used to
start the container. Luckily, Zodiac writes the original image name to a
label in the container metadata. If we find that Zodiac-specific label
on a running container we will use the associated value when trying to
determine if the container's image has changed.

058d6e5507 Turn DockerClient into dockerClient
No need to export this particular struct since we already have a public
Client interface available and a NewClient function which can be used to
instantiate the concrete struct.

dd80aa4a0d Support for --cleanup flag
The --cleanup flag will cause watchtower to automatically remove the old
image after a container is restart with a new image.

812fb60805 Handle errors without halting
If we receive an error while trying to shutdown/startup a particular
container we don't want to immediately terminate the current update
cycle. Instead we should continue processing the remaining containers
and simply log the error.

e21c21ec3b Account for latency in container removal
Under certain conditions when watchtower is monitoring a Docker Swarm
cluster there would be cases where an updated container could not be
started because the old hadn't yet been removed (name conflicts, mapped
port conflicts, etc). We suspect that this has something to do with the
async nature of swarm and even though we've asked the swarm master to
remove a container it may not be completely removed from the associated
node. The fix is to do some polling after the remove container call to
ensure that the container is truly gone before proceeding.

b7424e5c47 Fix issue where updated containers aren't stopped
Used 'break' instead of 'continue' resulting in the termination of the
stop container loop any time the watchtower container is encountered.

13ec7ac94e Fix aggressive image pulling
In cases where a container's image was specified without an explicit tag
watchtower was pulling ALL of the images. Fixed so that a ":latest" tag
is assumed if one hasn't been explicitly set.
