Configure log-format earlier, and small refactor
Some messages are logged before the logrus format was set,
therefore resulting in inconsistent log-message formatting
during startup;

Before this patch;

```
dockerd --experimental
WARN[0000] Running experimental build
INFO[2018-11-24T11:24:05.615249610Z] libcontainerd: started new containerd process  pid=132
INFO[2018-11-24T11:24:05.615348322Z] parsed scheme: "unix"                         module=grpc
...
```

With this patch applied;

```
dockerd --experimental
