This uses the previously unusued lib/stats.go code to return data
about container stats to the CRI API. Helpers have been built around
filtering based on the OCI API, and CPU stat reporting has been fixed.
No data on filesystem layer usage is returned at this time.
Fixes one-half of #1248

We had a bug in ImageStatus where we weren't returning the default
image user if set, thus running all containers as root despite a user
being set in the image config. We weren't populating the Username field
of ImageStatus.
This patch fixes that along with the handling of multiple images based
on the registry patch for multiple images.
It also fixes ListImages to return Username as well.

We need to record whether the sandbox is using hostnetwok because the
kubelet needs that information when computing pod changes. Without this
patch it could happen that a pod that's using host network is restarted
just because the sandbox's status isn't reporting that it's running
using host network.

We weren't setting the logPath of the sandbox when restoring sandboxes
and containers upon a crio restarts. That means that if you restart
CRI-O you get sandboxes with empty logPath. That means that when you're
starting a container in a restored sandbox you get a relative logPath
for the container:
sandboxLogPath: "/var/something"
- restore
sandboxLogPath: ""
- create container foo
containerLogPath: "foo_attempt.log"
With this patch we actually get an absolute path (which is correct):
sandboxLogPath: "/var/something"
- restore
sandboxLogPath: "/var/something"
- create container foo
containerLogPath: "/var/something/foo_attempt.log"

k8s already mounts /etc/hosts from /var/lib/kubelet/pods/<ID>/etc-hosts
even for host network. We shouldn't play with it unless we're running
from crictl for instance.

Having a separate function holding the details of this makes reading
createSandboxContainer easier.
While I was moving the code, I've also cleaned up two things:
* The nil capabilities check is now earlier, where before it had been
between the ALL handling and the non-ALL handling.
* I've added a capPrefixed variable to avoid having multiple
toCAPPrefixed calls per capability.

If a packager wants to be able to support addititional arguments on his
hook this will allow them to setup the configuration with these arguments.
For example this would allow a hook developer to add support for a --debug
flag to change the level of debugging in his hook.
In order to complete this task, I had to vendor in the latest
github.com://opencontainers/runtime-tools, which caused me to have to fix a
Mount and Capability interface calls

If server/Server.createSandboxContainer() fails after calling
server/Server.StorageRuntimeServer().CreateContainer(), cleanup logic in
server/Server.CreateContainer() won't try to clean it up, but we still
need to clean up the on-disk container and its layer.

Add an UntagImage() method to pkg/storage/ImageServer, which will check
if the passed-in NameOrID is a name. If so, it merely removes that name
from the image, removing the image only if it was the last name that the
image had. If the NameOrID is an image ID, the image is removed, as
RemoveImage() does.

The image's canonical reference is a name with a digest of the image's
manifest, so in imageService.ImageStatus() and
imageService.ListImages(), divide the image's name list into tagged and
digested values, and if we have names, add canonical versions.
In Server.ContainerStatus(), return the image name as it was given to us
as the image, and the image digested reference as the image reference.
In Server.ListImages(), be sure to only return tagged names in the
RepoTags field. In Server.ImageStatus(), also return canonical
references in the RepoDigests field.
In Server.PullImage(), be sure that we consistently return the same
image reference for an image, whether we ended up pulling it or not.

The tests are trying to read an write configuration files and check that the
fields are being set or saved properly.
A folder fixtures/ was created on server/ as well adding an example crio.conf
file to it.
Note: some extra paths about Vagrant and VSCode were added to gitignore.
