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.

container-storage-setup (Formerly docker-storage-setup) is being converted to
run with container runtimes outside of docker. Specifically we want to use it
with CRI-O/ocid. It does not know anything about the container runtimes it
is generating options for, so it generates them based on the storage CLI of
docker. I see no reason to have the storage option for ocid to be different
and we can just depracate the option for now.

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.

Vendor updated containers/image and containers/storage, along
with any new dependencies they drag in, and updated versions of other
dependencies that happen to get pulled in.
github.com/coreos/go-systemd/daemon/SdNotify() now takes a boolean to
control whether or not it unsets the NOTIFY_SOCKET variable from the
calling process's environment. Adapt.
github.com/opencontainers/runtime-tools/generate/Generator.AddProcessEnv()
now takes the environment variable name and value as two arguments, not
one. Adapt.

* Rename 'vendor/src' -> 'vendor'
* Ignore vendor/ instead of vendor/src/ for lint
* Rename 'cmd/client' -> 'cmd/ocic' to make it 'go install'able
* Rename 'cmd/server' -> 'cmd/ocid' to make it 'go install'able
* Update Makefile to build and install from GOPATH
* Update tests to locate ocid/ocic in GOPATH/bin
* Search for binaries in GOPATH/bin instead of PATH
* Install tools using `go get -u`, so they are updated on each run

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.

The client size field that we get back when we inspect an image is a
pointer to a number, not just a number, so we need to dereference it for
display.

We add 2 ocid options for choosing the CNI configuration and plugin
binaries directories: --cni-config-dir and --cni-plugin-dir.

Any binary that will be managing storage needs to initialize the reexec
package in order to be able to apply or read image layers.

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 subcommand is so that users can get a nice commented version of the
ocid configuration file. This comes from the "current" version of the
configuration (allowing somone to get their custom configuration as a
file). It also has a --default option.
In addition, update the tests to use `ocid config` so that we test this
setup (the loading and saving of the options).

The --config is merged with the default, and then is overridden by any
command-line options. Everything is organised to be in sub-tables so
that the sections are more clear.

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

This fixes a bug where --conmon wouldn't actually set the conmon binary
path, and also where we weren't setting CFLAGS while compiling conmon.

This lessens the Docker requirement for creating sandboxes (with the
requirement only existing for the actual image pulling that is done when
adding a container to a pod). The interface was chosen to match the
--conmon interface, so that the location of the pause binary can be
chosen by a user.
