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`.

You can use `linuxkit run vbox ...` to run using Oracle VirtualBox.
ISO or raw should be supported, and you can specify EFI.
Some more options may be useful in future.

This is a `moby.ImageConfig` struct which is marshalled into JSON and added as
the `org.mobyproject.config` label on the built image.
Convert `pkg/sysctl` as PoC.
