This was cluttering the logs on my clusters. The log should be just in
debug mode as we do for every request/response flow.

This is an optimization of our image pull code path. It's basically
how docker handles pulls as well. Let's be smart and check the image in
pull code path as well.
This also matches docker behavior which first checks whether we're
allowed to actually pull an image before looking into local storage.

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.

A goroutine is started to forward terminal resize requests
from the resize channel. Also, data is copied back/forth

The bug is silly if you have a master/node cluster where node is on a
different machine than the master.
The current behavior is to give our addresses like "0.0.0.0:10101". If
you run "kubectl exec ..." from another host, that's not going to work
since on a different host 0.0.0.0 resolves to localhost and kubectl
exec fails with:
error: unable to upgrade connection: 404 page not found
This patch fixes the above by giving our correct addresses for reaching
from outside.

Some runtimes like Clear Containers need to interpret the CRI-O
annotations, to distinguish the infra container from the regular one.
Here we export those annotations and use a more standard dotted
namespace for them.

node-e2e tests were failing in RHEL because, if running a privileged
container, we get all capability in the spec. The spec generator wasn't
filtering caps based on actual host caps, it was just adding _everything_.
This patch makes spec generator host specific.

During "Port forwarding" e2e tests, the following panic happened:
```
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x64981d]
goroutine 52788 [running]:
panic(0x1830ee0, 0xc4200100c0)

0xc4201cd0e0, ...)
```
The issue is `streamService.PortForward` assumed the first argument to
be the sandbox's infra container ID, thus trying to get it from memory
store using `.state.containers.Get`. Since that ID is of the sandbox
itself, it fails to get the container object from memory and panics in
`UpdateStatus`.
Fix it by looking for the sandbox's infra container ID starting from a
sandbox ID.

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.

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.)

Because kubelet will create broken symlinks for logPath it is necessary

Interleaving asynchronous updates with pod or container creations can
lead to unrecoverable races and corruptions of the pod or container hash
tables. This is fixed by serializing update against pod or container
