This is mostly used with Systemd, which really wants to manage
CGroups itself when managing containers via unit file.

This change adds the following annotation to every container created by
podman:
```json
"Annotations": {
"io.containers.manager": "libpod"
}
```
Target of this annotaions is to indicate which project in the containers
ecosystem is the major manager of a container when applications share
the same storage paths. This way projects can decide if they want to
manipulate the container or not. For example, since CRI-O and podman are
not using the same container library (libpod), CRI-O can skip podman
containers and provide the end user more useful information.
A corresponding end-to-end test has been adapted as well.

Previously, we only did this for volumes created at the same time
as the container. However, this is not correct behavior - Docker
does so for all named volumes, even those made with
'podman volume create' and mounted into a container later.

This isn't included in Docker, but seems handy enough.
Use the new API for 'volume rm' and 'volume inspect'.

When volume options and the local volume driver are specified,
the volume is intended to be mounted using the 'mount' command.
Supported options will be used to volume the volume before the
first container using it starts, and unmount the volume after the
last container using it dies.
This should work for any local filesystem, though at present I've
only tested with tmpfs and btrfs.

Add '.To(BeTrue())' to 'Expect(' statements in unit tests that
are missing them. These tests weren't being compared to anything,
thus reporting false positives.

crun emits wildly different error messages than runc in
two cases:
podman run ... /no/such/path (enoent)
podman run ... /etc (trying to exec a directory)
Deal with it by getting the runtime from 'podman info' and,
if crun, changing what we expect.
There may be more tweaks needed to get system tests working
with crun, but right now podman rawhide is too broken to
have any hope of finding them all.

when running in rootless mode, --device creates a bind mount from the
host instead of specifying the device in the OCI configuration. This
is required as an unprivileged user cannot use mknod, even when root
in a user namespace.

This will require a 'podman system renumber' after being applied
to get lock numbers for existing volumes.
Add the DB backend code for rewriting volume configs and use it
for updating lock numbers as part of 'system renumber'.

podman cp has had some unexpected bugs, and still has
some surprising behavior. It looks like this part of
the code is fragile. Add tests to try to prevent
future breakages.
Note that two of the new tests are disabled (skipped)
until #3829 gets fixed.

Update the CNI configuration instructions to line up with
the changes introduced in #3868. Also do a bit less documentation
of the configuration and point to the GitHub project so we won't
get out of sync in the future.

Support generating systemd unit files for a pod. Podman generates one
unit file for the pod including the PID file for the infra container's
conmon process and one unit file for each container (excluding the infra
container).
Note that this change implies refactorings in the `pkg/systemdgen` API.

Before, if the container was run with a specified user that wasn't root, exec would fail because it always set to root unless respecified by user.
instead, inherit the user from the container start.

The priv test added to the build test in June runs an 'apk'
command which, unavoidably, has to fetch stuff from the net.
This is slow and unreliable, and periodically leads to
timeout failures. Worse, when this happens, some sort of
invisible buildah-only container gets left behind that leads
to failures in subsequent tests when trying to reset to
known state.
Imperfect workaround: try a 240-second timeout (up from 60)
when running apk. As backup, add a custom teardown() which
attempts to force-remove all containers and any new images.

This is a breaking change and modifies the resulting image name when
pulling from an directory via `oci:...`.
Without this patch, the image names pulled via a local directory got
processed incorrectly, like this:
```
> podman pull oci:alpine
> podman images
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/oci alpine 4fa153a82426 5 weeks ago 5.85 MB
```
We now use the same approach as in the corresponding [buildah fix][1] to
adapt the behavior for correct `localhost/` prefixing.
[1]: https://github.com/containers/buildah/pull/1800
After applying the patch the same OCI image pull looks like this:
```
> ./bin/podman pull oci:alpine
> podman images
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/alpine latest 4fa153a82426 5 weeks ago 5.85 MB
```
End-to-end tests have been adapted as well to cover the added scenario.
