When running cri-tests with cri-o, I found out that cri-o panicked
immediately with the following message. Fix it by accessing to the
labels map only if it's non-nil.
```

sandbox: correctly init selinux labels
First, we weren't correctly initializing selinux labels. If any of
(level, user, role, type) was missing from kube selinux options, we
were erroring out. This is wrong as kube sends just `level=s0`
sometimes and docker itself allows `--security-opt label=level:s0`.
This patch directly initializes selinux labels, correctly, and adds a
test to verify it.

test: testdata: use container_runtime_t selinux type
RHEL SELinux policy doesn't have `container_t` type but we're using it
in our fixtures. That means Fedora integration tests pass because
`container_t` is in Fedora's container policy but RHEL is broken.
Fix it by using `container_runtime_t` which is aliased in Fedora policy
to `container_t`.

Kubelet can send cap add/drop ALL. Handle that in CRI-O as well.
Also, this PR is re-vendoring runtime-tools to fix capabilities add to
add caps to _all_ caps set **and** fix a shared memory issue (caps set
were initialized with the same slice, if one modifies one slice, it's
reflected on the other slices, the vendoring fixes this as well)

Add new directory /etc/crio/hooks.d, where packagers can drop a json config
file to specify a hook.
The json must specify a valid executable to run.
The json must also specify which stage(s) to run the hook:
prestart, poststart, poststop
The json must specify under which criteria the hook should be launched
If the container HasBindMounts
If the container cmd matches a list of regular expressions
If the containers annotations matches a list of regular expressions.
If any of these match the the hook will be launched.

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.

Found out that during OpenShift testing, node was trying to remove
containers (probably in a bad state) and was failing the removal with
this kind of error:
E0828 13:19:46.082710 1235 kuberuntime_gc.go:127] Failed to remove

I believe it's ok to ignore this error as it may happen conmon will
fail early before exit file is written.

We calculate these values at container creation time and store
them in the container object as they are requested during container

Containers running in kubernetes currently do not specify options
for mount propagation and whether to bind or rbind the mount point.
Since docker defaults to bind and rbind, we should match their

The storage library uses github.com/pkg/errors to wrap errors that it
returns from many of its functions, so when passing them to
os.IsNotExist() or comparing them to specific errors defined in the
storage library, unwrap them using errors.Cause().
