eacce1d52e Use overlay for writeable containers
Previously we would sneakily remount as `rw` but of course you can't
really do that on a truly immutable filesystem.

See https://github.com/moby/tool/pull/129 for the `moby` side.

8eb6709a3c containerd: Bump to new alpine (with v1.0.0-alpha2)
The logrus import path has changed, so adjust. Also there is a minor API change
to the containerd.IOCreation() function spec, it now takes a string id which we
can ignore.

cb2ca4ef66 Switch runc and containerd startup to be entirely Go
At present they use a small shared function called "prepare"
that does the read-write remounts, that I will switch to doing overlay
mounts soon.

e40db14598 Make service start up containerd and services
This moves most of the initialisation of containers to the
service init in the `service` command.

Still leaves remounting root file systems read only but this
will go away shortly. Another step closer to removing shell
scripts in base system.

b3db1a887c Update to containerd v1.0.0-alpha1
This is actually containerd#1141 rebased onto v1.0.0-alpha1.

The `dist` command has been integreated into `ctr` and so is removed, including
from the getty and sshd bind mounts and the test which uses it is updated..

There is no change to the version of runc vendored by containerd, so this is
unchanged.

538c8b5a7b containerd: Add a service command to cleanup stale containers on boot
This may occur if /var/lib/container happens to be on persistent storage.

5833d1b6bc init: replace ctr with a custom client using the containerd client library
Currently it supports only `service start <SERVICE>`, but it could grow e.g.
`stop`, `exec` etc in the future (although you can still use `ctr` for those).

In order to be able to use go-compile.sh the containerd build needs to move
from /root/go to /go as the GOPATH.

The vendoring situation is not ideal, but since this tool wants to be an exact
match for the containerd it seems tollerable to reuse its vendoring.
