This commit allows for loading an OCI image tarball before running an
OCI backed Shepherd service. It does so by adding a one shot Shepherd
service to the dependencies of the OCI backed service that at boot runs
docker load on the tarball.
* gnu/services/docker.scm (oci-image): New record;
(lower-oci-image): new variable, lower it;
(string-or-oci-image?): sanitize it;
(oci-container-configuration)[image]: allow also for oci-image records;
(oci-container-shepherd-service): use it;
(%oci-image-loader): new variable.

The oci-container-configuration supports two user fields: one is the
user, from the host system, under whose authority the OCI-backed
Shepherd service is run; the other is an optional user/UID that can be
passed to the docker run invokation to override the user defined in the
OCI image.
The user from the host system is incorrectly passed to docker run
command, this patches reverts the incorrect behavior and passes the
correct container-user field value.
* gnu/services/docker.scm (oci-container-configuration): Fix the user
passed to the docker run invokation.

cgroup v2 is the next generation of the control groups API. This patch
replaces the cgroup v1 file systems with the unified cgroup v2 file
system.
cgroup v2 allows for things like containerd/podman to run rootless
containers and opens guix system up to running things like Kubernetes.
Thanks to Hilton Chain <hako@ultrarare.space> for suggesting the Docker
service change.
* gnu/system/file-systems.scm (%control-groups): Change to a single
"cgroup2" mount point.
* gnu/services/docker.scm (docker-shepherd-service): Trim 'requirement'
field accordingly.

This commit fixes error 'time="2020-10-16T…" level=error msg="Handler for POST
/v1.40/containers/…/start returned error: failed to start shim: exec:
\"containerd-shim\": executable file not found in $PATH: unknown"'.
* gnu/services/docker.scm
(containerd-shepherd-service): Add "containerd-shim" to PATH.
The userland proxy option does not properly disable the userland proxy when
set to false. Docker defaults to enabling the userland proxy if the option is
unset on the command line.
* gnu/services/docker.scm (docker-shepherd-service): Properly handle the
'enable-proxy?' option.
