`image` as a variable/field name becomes too redundant and difficult to
grep for. Switching to `imageServer` makes for more readable code.

When powering off the system, we want the ocid service, to shutdown
all containers running on the system so they can cleanup properly
This patch will cleanup all pods on poweroff.
The ocid-shutdown.service drops a file /var/run/ocid.shutdown when the system
is shutting down. The ocid-shutdown.service should only be executed at system
shutdown.
On bootup sequence should be
start ocid.service
start ocid-shutdown.service (This is a NO-OP)
On system shutdown
stop ocid-shutdown.service (Creates /var/run/ocid.shutdown)
stop ocid.service (Notices /var/run/ocid.service and stops all pods before exiting.)

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}.

Now that conmon splits std{out,err} for !terminal containers, ExecSync
can parse that output to return the correct std{out,err} split to the
kubelet. Invalid log lines are ignored but complained about.

While it's not currently possible to do this for terminal=true
containers, for !terminal containers we can create separate pipes for
stdout and stderr, and then log them separately. This is required for
k8s's conformance tests.

It's 2017, let's not stick with C89 (also for some reason the Travis
environment has a different -std= default value than my local machine).

The CRI requires us to prepend (timestamp, stream) to every line of the
output, and it's quite likely (especially in the !terminal case) that we
will read more than one line of output in the read loop.
So, we need to write out each line separately with the prepended
timestamps. Doing this the simple way (the final part of the buffer is
written partially if it doesn't end in a newline) makes the code much
simpler, with the downside that if we ever switch to multiple streams
for output we'll have to rewrite parts of this.
In addition, drop the debugging output of cri-o for each chunk read so
we stop spamming stderr. We can do this now because 8a928d06e7
("oci: make ExecSync with ExitCode != 0 act properly") actually fixed
how ExecSync was being handled (especially in regards to this patch).

Previously we returned an internal error result when a program had a
non-zero exit code, which was incorrect. Fix this as well as change the
tests to actually check the "ExitCode" response from ExecSync (rather
than expecting ocic-ctr to return an internal error).

Since we no longer fall back to the noop plugin when
CNI configuration files are missing, and since the default
sandbox_config.json test file is running without host
networking, we must install the bridge and loopback
configuration files by default for tests to pass.

We need to support cases where InitCNI() is called before
any CNI configuration files have been installed. This is
for example happening when deploying a k8s cluster with kubeadm.
kubeadm will start the DNS pod and it is left to the caller to
pick a network overlay and create the corresponding pods, that
will typically install a CNI configuration file first.
Here we address that issue by doing 2 things:
- Not returning an error when the default CNI config files
directory is empty.
- If it is empty, we start a monitoring thread (fsnotify based)
that will synchronize the network configuration when a CNI
file is installed there.

As of containernetworking/cni commit 1b9caefba5670c59e0ccbf0b008d88da52a7d498,
the script to build has changed from 'build' to 'build.sh' which broke our
integration tests. Change the integration test Dockerfile to update this path,
and update the tutorial for good measure. Pin to current master to ensure this
breakage doesn't happen again.

Because kubelet will create broken symlinks for logPath it is necessary
to remove those symlinks before we attempt to write to them. This is a
temporary workaround while the issue is fixed upstream.

CRI requires us to timestamp our logs line-by-line by specifying whether
the line came from std{out,err} and the time at which the log was

While pipes have their downsides, it turns out that socketpair(2) will
break any program that tries to open /dev/std{out,err} for writing
(because they're symlinked to /proc/1/fd/{1,2} which will cause lots of
fun issues with sockets).
