When go-1.11beta1 is used for building, the following error is
reported:
> 14:56:20 daemon\graphdriver\lcow\lcow.go:236: Debugf format %s reads
> arg #2, but call has 1 arg
While fixing this, let's also fix a few other things in this
very function (startServiceVMIfNotRunning):
1. Do not use fmt.Printf when not required.
2. Use `title` whenever possible.
3. Don't add `id` to messages as `title` already has it.
4. Remove duplicated colons.
5. Try to unify style of messages.
6. s/startservicevmifnotrunning/startServiceVMIfNotRunning/
...
In general, logging/debugging here is a mess and requires much more
love than I can give it at the moment. Areas for improvement:
1. Add a global var logger = logrus.WithField("storage-driver", "lcow")
and use it everywhere else in the code.
2. Use logger.WithField("id", id) whenever possible (same for "context"
and other similar fields).
3. Revise all the errors returned to be uniform.
4. Make use of errors.Wrap[f] whenever possible.

This enables docker cp and ADD/COPY docker build support for LCOW.
Originally, the graphdriver.Get() interface returned a local path
to the container root filesystem. This does not work for LCOW, so
the Get() method now returns an interface that LCOW implements to
support copying to and from the container.

This changes the graphdriver to perform dynamic sandbox management.
Previously, as a temporary 'hack', the service VM had a prebuilt
sandbox in it. With this change, management is under the control
of the client (docker) and executes a mkfs.ext4 on it. This enables
sandboxes of non-default sizes too (a TODO previously in the code).
It also addresses https://github.com/moby/moby/pull/33969#discussion_r127287887
Requires:
- go-winio: v0.4.3
- opengcs: v0.0.12

This changes the LCOW driver to support both global SVM lifetime and
per-instance lifetime. It also corrects the scratch implementation.
