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)

When performing a tag, if a shortname was provided, tag.go would
preprend docker.io to the shortname through the ParseNormalized
function. Here we work around that such that is a short name
and tag are provided, the resulting tag will be shortname:tag. If
a shortname is provided without a tag, we append "latest" as the
tag.
Added specific tag tests too

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.

The syscall package is locked down and the comment in [1] advises to
switch code to use the corresponding package from golang.org/x/sys. Do
so and replace usage of package syscall where possible (leave
syscall.SysProcAttr and syscall.Stat_t).

This will also allow to get updates and fixes just by re-vendoring

The test "ctr execsync std{out,err}" from ctr.bats works with runc,
but the semantics behind is wrong.
We should not be able to execute a new process on a container which
has not been previously started. That's why this patch adds a call
to start the container.
Moreover, we don't want to be able to execute a new process on a
container that has already returned because its workload is done.
For that reason, we need to force the container workload to be a
"sleep 10" to ensure it is still running when the call to "exec"
is issued.

This patch isn't adding a test for /etc/hosts as that requires host
network and we don't want to play with host's /etc/hosts when running

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.

conmon has many flags that are parsed when it's executed, one of them
is "-c". During PR #510 where we vendor latest kube master code,
upstream has changed a test to call a "ctr execsync" with a command of
"sh -c commmand ...".
Turns out:
a) conmon has a "-c" flag which refers to the container name/id
b) the exec command has a "-c" flags but it's for "sh"
That leads to conmon parsing the second "-c" flags from the exec
command causing an error. The executed command looks like:
conmon -c [..other flags..] CONTAINERID -e sh -c echo hello world
This patch rewrites the exec sync code to not pass down to conmon the
exec command via command line. Rather, we're now creating an OCI runtime
process spec in a temp file, pass _the path_ down to conmon, and have
runc exec the command using "runc exec --process
/path/to/process-spec.json CONTAINERID". This is far better in which we
don't need to bother anymore about conflicts with flags in conmon.
Added and fixed some tests also.

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.

If an image that we're pulling from a registry has a digest in its
reference, use that to construct the destination image's reference.
This should help us detect cases where the image has previously been
pulled.
When we have a filter to use when listing images, expand it into a
reference so that we can properly match against names of images that
we've previously stored using fully expanded references.

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}.
