Previously only `/var` was `rshared` but some people need to share
mounts in `/opt` etc so let us make everything `rshared` for now.

The sha1 tag should be sufficient to uniquely identify the image
and the sha256 versions are just very long...

Added to Docker example as Swarm mode likes time sync.
Note uses pool.ntp.org at present, on some providers it
should use a different source.
Constraints not enabled as they seem to have an issue;
possibly trying to set before network is up.

Instead of mounting a new filesystem, revert to doing a `rw` bind.
However do not make `/` `rshared`, just `/var` as that is where we expect
filesystems to be mounted for persistence. Also only make the actual
container rootfs writeable, not the whole directory.

As suggested by @shykes these are clearer
- onboot for things that are run at boot time to completion
- services for persistent services

Also add ca-certificates to base, needed to use `dist` to pull.
Make two stage builds for `containerd` and `runc` so they have a
from `scratch` second stage.

This works and runs containers now, if you eg `runc exec` into it.
Needs a few tweaks for rlimits, but will pull and run containers.
Will integrate better with ssh/dev containers to make more usable.
For a simple test use
```
./bin/moby build examples/docker.yml
./bin/moby run hyperkit -disk-size 100 docker
```
