Remove containerd specific parts of the plugin package to prepare its
move out of the main repository. Separate the plugin registration
singleton into a separate package.
Separating out the plugin package and registration makes it easier to
implement external plugins without creating a dependency loop.

This migrates uses of github.com/opencontainers/runc/libcontainer/user
to the new github.com/moby/sys/user module, which was extracted from
runc at commit [opencontainers/runc@a3a0ec48c4].
This is the initial release of the module, which is a straight copy, but
some changes may be made in the next release (such as fixing camel-casing
in some fields and functions (Uid -> UID).

This "soft" deprecates the package, but keeps the local uses of the package,
which can make backporting this to release-branches easier (we can
still move all uses in those branches as well though).

runc, as mandated by the runtime-spec, ignores unknown fields in the
config.json. This is unfortunate for cases where we _must_ enable that
feature or fail.
For example, if we want to start a container with user namespaces and
volumes, using the uidMappings/gidMappings field is needed so the
UID/GIDs in the volume don't end up with garbage. However, if we don't
fail when runc will ignore these fields (because they are unknown to
runc), we will just start a container without using the mappings and the
UID/GIDs the container will persist to volumes the hostUID/GID, that can
change if the container is re-scheduled by Kubernetes.
This will end up in volumes having "garbage" and unmapped UIDs that the
container can no longer change. So, let's avoid this entirely by just
checking that runc supports idmap mounts if the container we are about
to create needs them.
Please note that the "runc features" subcommand is only run when we are
using idmap mounts. If idmap mounts are not used, the subcommand is not
run and therefore this should not affect containers that don't use idmap
mounts in any way.

The reference/docker package was a fork of github.com/distribution/distribution,
which could not easily be used as a direct dependency, as it brought many other
dependencies with it.
The "reference' package has now moved to a separate repository, which means
we can replace the local fork, and use the upstream implementation again.
The new module was extracted from the distribution repository at commit:
