Default to deploying the config version

If we don't supply a version when deploying we'll use the result of
docker image ls to decide which image to boot. But that doesn't
necessarily correspond to the one we have just built.

E.g. if you do something like:

```
mrsk deploy        # deploys git sha AAAAAAAAAAAAAA
git commit --amend # update the commit message
mrsk deploy        # deploys git sha BBBBBBBBBBBBBB
```

In this case running `docker image ls` will give you the same image
twice (because the contents are identical) with tags for both SHAs but
the image we have just built will not be returned first. Maybe the order
is random, but it always seems to come second as far as I have seen.

i.e you'll get something like:

```
REPOSITORY    TAG              IMAGE ID       CREATED          SIZE
foo/bar       AAAAAAAAAAAAAA   6272349a9619   31 minutes ago   791MB
foo/bar       BBBBBBBBBBBBBB   6272349a9619   31 minutes ago   791MB
```

Since we already know what version we want to deploy from the config,
let's just pass that through.
