- use the mkimage hashes that we had in LinuxKit as more up to date than tool.
- update docs
- move the code from moby under src/cmd/linuxkit

This process connects to memlogd and streams logs to individual files,
one per log. It keeps track of how many bytes have been written to each
file and rotates when the file size exceeds a defined threshold.
By default the maximum size of each file before rotation is 1MiB and
we keep up to 10 files per log.

Switch to a more formally-specified `kmsg`-style format for reading
the logs.
- update the spec in docs/logging.md
- check for bad names in pkg/memlogd with unit test

Since I struggled to understand and find information about how to
troubleshoot a running linuxkit instance, I propose to add these two
FAQ entries.
The first one explains why it is possible to not see the `containerd` or
`init` outputs at boot in the console.
The second one gives a few `ctr` example to list containers, running
containers or how to open a shell in a given container.

the kernel series name. Otherwise the script in kernel/Dockerfile
will not apply it. So the example file name should be
`config-4.9.x-x86_64-foo` instead of `config-foo`.

This describes more accurately that the example exposes
containerd to the host.
Also adjust platform-hyperkit.md

This adds a namespace field to override the LinuxKit containerd
default namespace, in case you want to run a container in another
namespace.
Needs a patch in LinuxKit to implement this that I will open soon.

Annotations do not do anything by default but get passed through to the runtime,
which can be useful. I never metadata I didn't like...
Also fix sysctl to be a map in the validation, not an array. I can't see any
examples using this in LinuxKit, but this matches OCI so is correct.

This allows the `linuxkit/kubernetes` "image-cache" packages to use a standard
`linuxkit pkg build` based flow rather than requiring surrounding scaffolding.
Fixes#2766. Compared with the original (actually, the second) proposal made in
issue #2766, the field is `docker-images` rather than `images` to allow for
future inclusion of e.g. `containerd-images`.
