Basically none of the clever storage drivers will work when we're on top
of AUFS, so if we find ourselves in that situation when running tests,
default to storage options of "--storage-driver vfs".

The syscall package is locked down and the comment in [1] advises to
switch code to use the corresponding package from golang.org/x/sys. Do
so and replace usage of package syscall where possible (leave
syscall.SysProcAttr and syscall.Stat_t).
[1] https://github.com/golang/go/blob/master/src/syscall/syscall.go#L21-L24
This will also allow to get updates and fixes just by re-vendoring
golang.org/x/sys/unix instead of having to update to a new go version.

The test "ctr execsync std{out,err}" from ctr.bats works with runc,
but the semantics behind is wrong.
We should not be able to execute a new process on a container which
has not been previously started. That's why this patch adds a call
to start the container.
Moreover, we don't want to be able to execute a new process on a
container that has already returned because its workload is done.
For that reason, we need to force the container workload to be a
"sleep 10" to ensure it is still running when the call to "exec"
is issued.

This patch isn't adding a test for /etc/hosts as that requires host
network and we don't want to play with host's /etc/hosts when running
make localintegration on our laptops. That may change in the future

This patch fixes the following command:
kubectl run -i --tty centos --image=centos -- sh
The command above use to fail with:
/usr/bin/sh: /usr/bin/sh: cannot execute binary file
That's because we were wrongly assembling the OCI processArgs.
Thanks @alexlarsson for spotting this.
This patch basically replicates what docker does when merging container
config and image config. It also replicates how docker sets processArgs
for the OCI runtime.

conmon has many flags that are parsed when it's executed, one of them
is "-c". During PR #510 where we vendor latest kube master code,
upstream has changed a test to call a "ctr execsync" with a command of
"sh -c commmand ...".
Turns out:
a) conmon has a "-c" flag which refers to the container name/id
b) the exec command has a "-c" flags but it's for "sh"
That leads to conmon parsing the second "-c" flags from the exec
command causing an error. The executed command looks like:
conmon -c [..other flags..] CONTAINERID -e sh -c echo hello world
This patch rewrites the exec sync code to not pass down to conmon the
exec command via command line. Rather, we're now creating an OCI runtime
process spec in a temp file, pass _the path_ down to conmon, and have
runc exec the command using "runc exec --process
/path/to/process-spec.json CONTAINERID". This is far better in which we
don't need to bother anymore about conflicts with flags in conmon.
Added and fixed some tests also.

If we create a container using the image ID like
771cd5947d5ea4bf8e8f4900dd357dbb67e7b16486c270f8274087d182d457c6, then
a call to container_status will return that same ID for the "Image"
field in ContainerStatusResponse.
This patch matches dockershim behavior and return the first tagged name
if available from the image store.
This is also needed to fix a failure in k8s e2d tests.

If an image that we're pulling from a registry has a digest in its
reference, use that to construct the destination image's reference.
This should help us detect cases where the image has previously been
pulled.
When we have a filter to use when listing images, expand it into a
reference so that we can properly match against names of images that
we've previously stored using fully expanded references.

Now that we have support for split std{out,err}, make sure that execsync
will correctly handle the split stdio properly. In addition, extend the
ctr logging test to make sure that the regular container logging is also
split correctly. We can't test !terminal containers because we only have
a single console for both std{out,err}.

containers/storage is defaulting to /var/lib/containers/storage

container-storage-setup (Formerly docker-storage-setup) is being converted to
run with container runtimes outside of docker. Specifically we want to use it
with CRI-O/ocid. It does not know anything about the container runtimes it
is generating options for, so it generates them based on the storage CLI of
docker. I see no reason to have the storage option for ocid to be different
and we can just depracate the option for now.

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.

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.
