Also tweak the shell script a little and give the local and GCP
infrakit group different names.

`nested runc` unfortunately needs a lot of caps/privileged. The removal of `readonly: true` is also a bit unfortunate.

This makes the configuration simpler but requires us to be able
to set IP addresses on instances.
This also, for simplicity, reduces the number of nodes to 3.
The script does not make assumption about specific IP addresses,
but does assume that the nodes have IP addresses such as:
a.b.c.200, a.b.c.201, and a.b.c.202.

Make all the low-level init code synchronous to avoid weird blocks on `close`.
Also move the net and ctl file descriptor at the beginning of the fd space for
the calf.
The SDK also allow to spamn multiple exec calves, which will all have the same
fd map:
- 0: stdin = /dev/null
- 1: stdout = pipe to parent stdout
- 2: stderr = pipe to parent stderr
- 3: net = socketpair to parent "net" pipe
- 4: ctl = socketpair to parent "ctl" pipe

This forces us to bind mount /lib but will be replaced by calling the proper
bindings later on.

It is not necessary to bring up `eth0`, the program does it fine.
This means we can remove shell script, clean up build.

Instead of specifying the number of instances, provide a list
of IP addresses for instances. These are passed to the instance
plugin as LogicalID.

In #1485 I was still using a local mobylinux/init containing #1436, even though
I had included the necessary files in the swarmd container.
Switch to the current standard init package and drop the unnecessary bind.
Also `git add .gitignore` which I forgot last time too.

This is based on https://github.com/docker/swarmkit/pull/1965 which adds a
direct containerd executor to swarmkit. It is very much a work in progress.
With a suitable moby image (such as projects/swarmd/swarmd.yml) something like
this should work:
runc exec swarmd swarmctl service create --image docker.io/library/nginx:alpine --name nginx
runc exec swarmd swarmctl service ls

This just sets up the initial cluster via bootstrap.
It does *not* manage state changes correctly afterwards. If one
node crashes (get's killed) it InfraKit will start a new node,
but the new node does not join the cluster (and the old node
is not removed, either).

- Script to set up a DfM etcd for bootstrapping a cluser
- Custom/local etcd package for moby
derived from the official image with script to start etcd
- YAML file to create a etcd moby image
- README with current instructions
This has a bunch of stuff, including the discovery URL hard coded.

In the riddler change I changed "command" in the yaml to "args"
but did not change the files. In fact we basically used the
default command everywhere so this did not actually break.
Remove the unnecessary "command" lines to simplify yaml.
Revert the command to args change for now as I think I prefer
command, but its easier to switch now. Need to think if the
entrypoint/command distinction matters before finalizing.
