This commit introduces a new option - `keyname` - to the OpenStack
runner, which allows the user to specify the name of a keypair they want
to associate with the instance at the time of creation.

This removes more shell scripts to improve maintainability.
This now also works correctly in userspace, so it can be used for
running LinuxKit images in Docker and other such use cases.
It is a literal conversion of the shell scripts with a few small
tweaks.

With the master tailoring for docker now being in docker-master.yml,
kube-master and kube-node are identical, so just use a single kube.yml.
The reference to kube-master.yml in README.md is obsolete, so just drop it.

This allows cri-containerd and docker based systems to pass the correct options
via composition of yml files, while keeping the kubelet service stanza common.
Since bind mounts are not conditional on the presence of the source we need to
create an empty file in the docker case.

This doesn't seem to be necessary when using Docker Engine as the CRI backend,
but in general it is.
The sysctl container must be writeable to allow the
/etc/sysctl.d/01-kubernetes.conf mount point to be created. See #2503.

Depending on the configuration/components used the system can expect to be able
to share `/var/run/netns` (=`/run/netns` via symlink) bind mounts with other
system level containers, which requires exposing those to the host.
This doesn't appear to be needed when using Docker engine but it is with
cri-containerd.

Kubernetes assumes (for now) that various paths are valid at the host level to
be mounted into containers, including /opt/cni and /etc/cni.
We cannot (easily) use symlinks here because the weave.yml mounts /opt and /etc
rather than /opt/cni and /etc/cni (this seems likely to be common pattern). So
if /etc/cni were a symlink to the persistent disk (under /var/lib) then it will
be dangling link within the weave container.
So add bind mounts to the runtime configuration of the kubernetes image. This
also means we must create the target mount points in the yml.

This avoids a slightly tricky sequence of nested bind mounts by just unpacking
a tarball on boot (with a stamp so it only happens once).

- Extract common portions from the YAML file
This makes kernel/init/runc updates easier as only one
files needs changing
- Rename test-ns.yml to test.yml to make it more in line
with the other tests
- Use '-name' in the moby build
- Simplify cleanup

- Consistently use env variables for names
- Make sure temporary files are removed (the 'create'
images were left behind)

Build tests don't need the 'find' nor 'rm -r' as they don't
create directories.
There is no need to delete the 'test.yml' file in
the output tests.
Consistently use NAME as the name argument

For example to tell kubelet to use cri-containerd:
command: ["/usr/bin/kubelet.sh", "--container-runtime=remote", "--container-runtime-endpoint=unix:///var/run/cri-containerd.sock"]

Not having to redo the kubeadm-init.sh step massively speeds up the test/dev
cycle. Having the same MAC (and hence same IP) is useful there too since you
don't need to figure out the mac on each boot.

The sock-shop demo[0] requires around 5G of images on a worker node and 3G of
RAM (if there is only one worker node and therefore everything runs on that
node).
Since the master is more than happy with the 4G disk and 1G RAM it is given
today split the settings into master and node specific and bump only the
latter.
KUBE_PORT_BASE is unused and was already removed in 54ddde0d43 but
accidentally reintroduced (by me) in 62aa9248a4, whack it again.

- Update LCOW to latest rev of OpenGCS

These are the recommended patches for 4.12 for Hyper-V sockets
and LCOW. Based on: https://github.com/Microsoft/opengcs/pull/138
This also includes a cherry-pick from upstream which fixes the
ext4/nvdimm/pax failures we have seen since 4.11.2.
