kpod must parse the crio configuration file or the storage
is not set up correctly. By default it is not. We now read
/etc/crio/crio.conf in as the configuration file unless it is
overriden by the user and the global -c|--config switch.

Make getStore() take a config struct from which it pulls the store
options, then update the kpod commands so that they call getConfig()
and pass the config into getStore()

Container runtimes provide different levels of isolation, from kernel
namespaces to hardware virtualization. When starting a specific
container, one may want to decide which level of isolation to use
depending on how much we trust the container workload. Fully verified
and signed containers may not need the hardware isolation layer but e.g.
CI jobs pulling packages from many untrusted sources should probably not
run only on a kernel namespace isolation layer.
Here we allow CRI-O users to define a container runtime for trusted
containers and another one for untrusted containers, and also to define
a general, default trust level. This anticipates future kubelet
implementations that would be able to tag containers as trusted or
untrusted. When missing a kubelet hint, containers are trusted by
default.
A container becomes untrusted if we get a hint in that direction from
kubelet or if the default trust level is set to "untrusted" and the
container is not privileged. In both cases CRI-O will try to use the
untrusted container runtime. For any other cases, it will switch to the
trusted one.

The ocid project was renamed to CRI-O, months ago, it is time that we moved
all of the code to the new name. We want to elminate the name ocid from use.
Move fully to crio.
Also cric is being renamed to crioctl for the time being.

The main purpose of these tests is to make sure that the log actually
contains output from the container. We don't test the timestamps or the
stream that's stated at the moment.

After change in `Makefile` at #304 where `PREFIX`

containers/storage is defaulting to /var/lib/containers/storage
for image and containers storage. It is also defaulting to
/var/run/containers/storage for all runtime. The defaults
for CRI-O should match so that lots of other tools that use
containers/storage can share the same storage.

We have moved selinux support out of opencontainers/runc into its
own package. This patch moves to using the new selinux go bindings.

Not all runtimes are able to handle some of the kubelet
security context options, in particular the ones granting
host privileges to containers.
By adding a host privileged runtime path configuration, we
allow ocid to use a different runtime for host privileged
operations like e.g. host namespaces access.

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.

The default configuration can only be accessed from the cmd/server
package, which cannot be imported (since it's a "package main").
This change promotes DefaultConfig() to the "server" package.

While logDir isn't currently used (until the conmon implementation
lands) it's probably not a great idea to hardcode our defaults. The main
issue with this setting is that the kubelet can override it at will.

It's a bit odd to have ImageStore be part of the config and yet we don't
allow people to modify it. However, leave it out of the commented
version because it's currently unused.

This paves the way for having a configuration file that is loaded rather
than everything being set via the command-line.
