The CRI doesn't expect us to implicitly pull an image if it isn't
already present before we're asked to use it to create a container, and
the tests no longer depend on us doing so, either.
Limit the logic which attempts to pull an image, if it isn't present, to
only pulling the configured "pause" image, since our use of that image
for running pod sandboxes is an implementation detail that our clients
can't be expected to know or care about. Include the name of the image
that we didn't pull in the error we return when we don't pull one.

Add a basic tool for copying images from one location to another,
optionally adding a name if it's to local storage. Ideally we could use
skopeo for this, but we don't want to build it.
Use it to initially populate the test/testdata/redis-image directory, if
it's not been cleaned out, with a copy of "docker://redis:latest", and
to copy it in to the storage that ocid is using before we start up ocid.

Add tests which exercise image pulling, listing, and removal. When running
tests, prepopulate the store with an image with the default infrastructure
container's name, using the locally-built "pause" binary, so that tests won't
have to pull it down from the network.

Use containers/storage to store images, pod sandboxes, and containers.
A pod sandbox's infrastructure container has the same ID as the pod to
which it belongs, and all containers also keep track of their pod's ID.
The container configuration that we build using the data in a
CreateContainerRequest is stored in the container's ContainerDirectory
and ContainerRunDirectory.
We catch SIGTERM and SIGINT, and when we receive either, we gracefully
exit the grpc loop. If we also think that there aren't any container
filesystems in use, we attempt to do a clean shutdown of the storage
driver.
The test harness now waits for ocid to exit before attempting to delete
the storage root directory.

* Rename 'vendor/src' -> 'vendor'
* Ignore vendor/ instead of vendor/src/ for lint
* Rename 'cmd/client' -> 'cmd/ocic' to make it 'go install'able
* Rename 'cmd/server' -> 'cmd/ocid' to make it 'go install'able
* Update Makefile to build and install from GOPATH
* Update tests to locate ocid/ocic in GOPATH/bin
* Search for binaries in GOPATH/bin instead of PATH
* Install tools using `go get -u`, so they are updated on each run

We create 2 pods in 2 different networking namespace and
we check if we can ping one from the other.

We create temporary CNI networking configurations and run 2
functional tests:
- Verify that the networking namespace interface has a valid CIDR
- Ping the networking namespace interface from the host

The rootfs that gets created needs to have an SELinux label that containers
can write to. Until they get native storage support, this patch will
force the entire storage pool to be labeled in such a way that confined
containers can read/write/execute the content.

This subcommand is so that users can get a nice commented version of the
ocid configuration file. This comes from the "current" version of the
configuration (allowing somone to get their custom configuration as a
file). It also has a --default option.
In addition, update the tests to use `ocid config` so that we test this
setup (the loading and saving of the options).

This lessens the Docker requirement for creating sandboxes (with the
requirement only existing for the actual image pulling that is done when
adding a container to a pod). The interface was chosen to match the
--conmon interface, so that the location of the pause binary can be
chosen by a user.
