fc84079db3 demo: Initial etcd cluster setup with InfraKit
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).

4b3422f76c demo: WIP for a local etcd setup
- 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.

57c75741e9 Revert Command->Args but remove from yaml where not needed
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.

065af9707c Replace riddler with code that constructs config.json directly
Generated largely from the specified config; small parts taken from `docker image inspect`,
such as the command line.

Renamed some of the yaml keys to match the OCI spec rather than Docker Compose as
we decided they are more readable, no more underscores.

Add some extra functionality
- tmpfs specification
- fully general mount specification
- no new privileges can be specified now

For nostalgic reasons, using engine-api to talk to the docker cli as
we only need an old API version, and it is nice and easy to vendor...

dfb078825b miragesdk: simplify the build of the calf binary
For now, use jbuilder to build the calf as well, this gives us a bit
more control than the mirage tool. We will switch back to the mirage
tool later on if we want to use more fancy backends (such as KVM).

faa9e1811d miragesdk: implement a simple binary RPCs for the control plane
The protocol allows the client to send concurrent RPCs to the server.
The server replies by keeping the client ID, and the client keeps a
dispatch table of queries to route the retries. By doing things like
that, the server has a strong control over resource allocation, so
a bad client cannot exhaust all the server memory.

Also add some simple tests for the serialization + wire protocol which
are all passing. Proper concurrency/resource exhaustion usage will be
added later.

b5a3d4b2aa miragesdk: rework the control plane protocol
Previously, the control plane was using HTTP client/server, that various people
found way too complex to run in a privileged container (for very good reasons).

So switching to a simpler binary protocol, using c-like structures. Will
probably switch to an other serialization protocol later (eg. protobuf
or cap-n-proto).

bb49cab9c2 kernel: add build config for the experimental "split kernel"
The aim of the split kernel is to introduce a level of intra-kernel
protection into the kernel so that, amongst other things, it can
offer lifetime guarantees over kernel code and data integrity.

These patches only wire in the kernel build from a 4.11-rc3 snapshot.
The userspace tools will follow shortly.  Instructions came via
https://github.com/linux-okernel/linux-okernel (linux-okernel branch)
and via @edwards-n and @t-koulouris.

The build can be done via `cd projects/okernel && make`.
