cmd/dist, cmd/ctr: end to end image pull
With this changeset, we now have a proof of concept of end to end pull.
Up to this point, the relationship between subsystems has been somewhat
theoretical. We now leverage fetching, the snapshot drivers, the rootfs
service, image metadata and the execution service, validating the proposed
model for containerd. There are a few caveats, including the need to move some
of the access into GRPC services, but the basic components are there.

The first command we will cover here is `dist pull`. This is the analog
of `docker pull` and `git pull`. It performs a full resource fetch for
an image and unpacks the root filesystem into the snapshot drivers. An
example follows:

``` console
$ sudo ./bin/dist pull docker.io/library/redis:latest
docker.io/library/redis:latest:                                                   resolved       |++++++++++++++++++++++++++++++++++++++|

INFO[0001] unpacking rootfs
```

Note that we haven't integrated rootfs unpacking into the status output, but we
pretty much have what is in docker today (:P). We can see the result of our pull
with the following:

```console
$ sudo ./bin/dist images
REF                            TYPE                                                 DIGEST                                                                  SIZE
docker.io/library/redis:latest application/vnd.docker.distribution.manifest.v2+json sha256:4c8fb09e8d634ab823b1c125e64f0e1ceaf216025aa38283ea1b42997f1e8059 1.8 kB
```

The above shows that we have an image called "docker.io/library/redis:latest"
mapped to the given digest marked with a specific format. We get the size of
the manifest right now, not the full image, but we can add more as we need it.
For the most part, this is all that is needed, but a few tweaks to the model
for naming may need to be added. Specifically, we may want to index under a few
different names, including those qualified by hash or matched by tag versions.
We can do more work in this area as we develop the metadata store.

The name shown above can then be used to run the actual container image. We can
do this with the following command:

```console
$ sudo ./bin/ctr run --id foo docker.io/library/redis:latest /usr/local/bin/redis-server
1:C 17 Mar 17:20:25.316 # Warning: no config file specified, using the default config. In order to specify a config file use /usr/local/bin/redis-server /path/to/redis.conf

```

Wow! So, now we are running `redis`!

There are still a few things to work out. Notice that we have to specify the
command as part of the arguments to `ctr run`. This is because are not yet
reading the image config and converting it to an OCI runtime config. With the
base laid in this PR, adding such functionality should be straightforward.

While this is a _little_ messy, this is great progress. It should be easy
sailing from here.

version: finish version setup
This setup will now correctly set the version number from the git tag.
When using `--version`, we will see the binary name, the package it was
built from and a git hash based on the tag:

```console
$./bin/dist -v
./bin/dist github.com/docker/containerd 0b45d91.m
```

Note that in the above example, if we set a tag of `v1.0.0-dev`, that
will show up in the version number, as follows:

```console
$./bin/dist -v
./bin/dist github.com/docker/containerd v1.0.0-dev
```

Once commits are made past that tag, the version number will be
expressed relative to that tag and include a git hash:

```console
$./bin/dist -v
./bin/dist github.com/docker/containerd v1.0.0-dev-1-g7953e96.m
```

Some these examples include a `.m` postfix. This indicates that the
binary was build from a source tree with local modifications.

We can add a dev tag to start getting 1.0 version numbers for test
builds.
