To collect CPU profile information added a flag `--cpu-profile`
which is a path to file where this collected information will be
dumped.

Reusing k8s existing implementation. This could be re-written
to do port-forwarding natively rather than relying on socat/nsenter.

We use the k8s remotecommand client API to create a
streaming executor, and then stream the executed process
into stdout/stderr.

`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).
