This is much more functional (includes networking).
Requires switching to an alpine base because CNI networking backends (such as
weave) can expect iptables binaries to be present, or may want to shell out to
scripts etc.

This changes the CLI specification for disks, as it needs to be able to
be repeated.
```
linuxkit run qemu -disk name,size=1G,format=qcow2 ...
```
Options may be omitted.
Currently other local backends may not support multiple disks, but this
can be added in future. Code for cloud backends has not changed as the
disk support is specific to the platform.

Uses the alpine base container. Networking is not disabled because we still
clone at build time.
No swarmd.yml update because the commit referenced here no longer exists in the
upstream repo after a force push. This will change in the next commit.

The existing set was randomly rather than carefully chosen, lets just be honest
and use "all" until the proper set can be determined.

Update everything including the current
linuxkit/containerd:b1766e4c4c09f63ac4925a6e4612852a93f7e73b to the new
linuxkit/containerd:deaf5bf838bf7f131c2287ecff3ed9835b0497e2.

This ovmf package is part of the community repository. We don't
want to "pollute" the Alpine base with it. Luckily it's juts a single
file which we can install and then copy to the base image.
The package is needed for qemu EFI boot.

This should make it easier to switch out `init` for other versions,
although the `getty` config still needs to be removed.
- use `/bin/rc.init` for start
- use `rc.shutdown` for stop
- make `rc.init` run other code.
- merge `containers` and `containerd` startup code

We don't actually build it here, we just use the alpine package, which is
already included in the linuxkit/alpine base.
Can be instantiated with a service stanza such as:
- name: qemu-ga
image: "linuxkit/qemu-ga:e5fbcf55926f6e1a96b3e49a392e547e8be1022c"
binds:
- /dev/vport0p1:/dev/vport0p1
The only functionality I've tested is to report IP addresses to the host (e.g.
via `virsh domifaddr`).
The image is configured to use `/dev/vport0p1` by default. If your VM image is
using a different port number then you can either incorporate the rename into
the bind ("/dev/vport1p1:/dev/vport0p1") or override the command with:
command: ["/usr/bin/qemu-ga", "-p", "/dev/vport1p1"]
The mdev tool appears to not create the symlinks which udev would provide
`/dev/virtio-ports/org.qemu.guest_agent.0` hence the need to hardcode the
potentially unstable `/dev/vportNp1`, `N` seems to depend on the number and
order of virtio devices in use. I don't know if it is possible to get mdev to
create these links. For reference the udev rule is:
SUBSYSTEM=="virtio-ports", KERNEL=="vport*", ATTR{name}=="?*", SYMLINK+="virtio-ports/$attr{name}"
See https://wiki.libvirt.org/page/Qemu_guest_agent for more info on the guest
agent.
A suitable stanza is added to `projects/swarmd/swarmd.yml` since that is where
I am using it.
