A light weight overlay implementation that emits working mounts is
demonstrated. One can prepare and commit changes. The diffs are
correctly held on disk.
The next step from here is to implement the changes methods and ensure
that we can work with the docker registry API.

We define the approach and API of the LayerManipulator. It provides a
model for a bare bones graph driver using a simplified snapshotting
model. Callers Prepare and Commit diff paths to build up a tree of
interelated layers, all without being coupled to the layer diff format
or an image runtime.

This commit cuts out the structure for defining grpc services for this
project. To provide compatibility with go package generation and support
reuse, we use a single protobuf file per package and make the import
paths relative to the GOPATH.
This first pass attempts to position the Mount type as the lingua franca
of ContainerKit. The Images service will provide paths prepared for use
as a set of mounts of the container service.
We'll need to merge the container service in place with new file defined
here.

The currently used go-grpc client is rather old (a commit from May).
Since then a GA release has been cut, so let's use that.

The create/start split left checkpoint/restore broken in that the create
side was calling runc restore, which fully restores the process to
operation, leaving a call to `runc start` as an error (process already
started). This patch skips process.Start as it is an unnecessary (and
wrong) step for a restored checkpoint.

That comment didn't seem to match the reality and confused me a bit. The
shim takes 3 arguments and the cwd is the containerd state directory.
I'm guessing it's a left over from the containerd split.

* gitignore: Use absolute paths
git status will only match the ignored path from the root of the
repository, a very slightly more accurate way to ignore those files.

* gitignore: Ignore the /output directory
Test artifacts are now generated in /output, so update the .gitignore
file accordingly.
