Previously the network policy yaml had to be hard-coded in the image.
This patch allows the policy to be added via the metadata directories:
- /var/config/cni/etc/net.d/
- /var/config/kube-system.init/

This has no kube object(s) but just arranges for the CNI configuration to be
written in the right place. The CNI bridge, loopback etc binaries are already
included since they are in the reference set.

KUBE_NETWORK now specifies a yml which is passed to the Moby tool, which can
introduce files into /etc/kubeadm/kube-system.init/ or do other things as it
likes.
In the case of weave this just adds the weave yaml to that directory. To avoid
too much confusion between weave.yml (Moby tool input) and `weave.yaml` (the
kubernetes `ServiceAccount`, `DeamonsSet` etc object specs) name the latter
`kube-weave.yaml`.

Building both BIOS and EFI variants is a waste of time in most cases, instead
just build whichever one is relevant to the platform (which currently means EFI
on Darwin and BIOS everywhere else).
At the same time make it possible to pass "KUBE_FORMATS" (a space separated
list of targets) to the build e.g. `make KUBE_FORMATS="iso-efi iso-bios"` will
preserve the behaviour prior to this patch.

Specifically ignore present-but-empty files entirely and ignore (but log)
failure to apply any one file.
Ignoring an empty file is useful because it means you can clobber a file which
might be referenced from an images binds without needing to override those
binds (since that generally means duplicating the whole lot which is annoying).
Ignoring any failures to apply means the rest gets applied and the rest of the
script (including untaint and the stamp file creation) still happen, resulting
in a system where the admin just has to address the failures rather than the
remaining updates. We touch a file to indicate failure generally plus one to
indicate the specific yaml which failed to apply.

Adding a `PRETTY_NAME` to this causes it to appear in the node information:
$ kubectl --namespace=kube-system get -o wide nodes
NAME STATUS ROLES AGE VERSION EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
linuxkit-b6e09efea36e Ready master 29m v1.8.0 <none> LinuxKit Kubernetes Project 4.9.53-linuxkit containerd://1.0.0-beta.1
Previously it would be `Unknown`.
A later yaml passed to `moby build` can override this by simply duplicating
the path.

Done as follows:
find -name build.yml | xargs dirname | while read d ; do
t=$(linuxkit pkg show-tag $d)
./scripts/update-component-sha.sh --image ${t%:*} ${t#*:}
done
git commit -s test pkg tools blueprints examples projects/kubernetes projects/swarmd docs linuxkit.yml Makefile src
This explicitly excludes projects/* which I did not know whether to update.
Then:
git reset --hard
for i in init runc containerd ca-certificates sysctl dhcpcd getty rngd ; do
o=$(git grep -h "\(image:\|-\) *linuxkit/$i:[0-9a-f]\{40\}" origin/master:linuxkit.yml | awk '// { print $2 }')
n=$(linuxkit pkg show-tag pkg/$i)
./scripts/update-component-sha.sh "$o" "$n"
done
git commit --amend projects
This updates any projects which were using components with the same hash as the
top-level linuxkit.yml.
