When enabled, it's desired for the podman-varlink process to startup on
boot or upon socket-activation, whichever happens first. However,
with `KillMode=none` systemd will never kill any podman-varlink
processes. This makes it easily possible for multiple podman-varlink
processes to be running, and fight each other to service a single socket.
---
For example:
Prior to this commit, this will result in four podman-varlink processes
being run:
```
systemctl enable io.podman.socket
systemctl enable io.podman.service
systemctl start io.podman.socket
systemctl start io.podman.service
systemctl start io.podman.service
```
Fix this by setting `KillMode=process` and `TimeoutStopSec=30` (default
is 90). This results in podman-varlink exiting on its own after a minute
of being idle (--timeout=60000). Alternatively, systemd will manage the
service stop by sending a SIGTERM, then if podman-varlink has not exited
within `TimeoutStopSec`, a SIGKILL will be sent.

When --cgroupns=private is used we need to mount a new cgroup file

when running in rootless mode and using systemd as cgroup manager
create automatically a systemd scope when the user doesn't own the
current cgroup.
This solves a couple of issues:
on cgroup v2 it is necessary that a process before it can moved to a
different cgroup tree must be in a directory owned by the unprivileged
user. This is not always true, e.g. when creating a session with su
-l.
Closes: https://github.com/containers/libpod/issues/3937
Also, for running systemd in a container it was before necessary to
specify "systemd-run --scope --user podman ...", now this is done
automatically as part of this PR.

Lookup was written before volume states merged, but merged after,
and CI didn't catch the obvious failure here. Without a valid
state, we try to unmarshall into a null pointer, and 'volume rm'
is completely broken because of it.

When constructing VM cache-images, the latest/greatest podman package is
installed to ensure all necessary dependencies are met. Prior to
testing source-built binaries, most of of the packaged files are removed.
However, if the `io.podman` service or socket is enabled/running, it
could cause the packaged podman and varlink binaries to be both resident
and cached. Since this condition would cause very difficult to diagnose
behaviors, add preventative measures to ensure these services are absent
prior to removing packaged podman files.

Podman is not the only user of containers/storage, and as such we
cannot rely on our database as the sole source of truth when
pruning images. If images do not show as in use from Podman's
perspective, but subsequently fail to remove because they are
being used by a container, they're probably being used by Buildah
or another c/storage client.
Since the images in question are in use, we shouldn't error on
failure to prune them - we weren't supposed to prune them in the
first place.

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.

Do not require 0755 permissons for the ~/.config directory but require
at least 0700 which should be sufficient. The current implementation
internally creates this directory with 0755 if it does not exist, but if the
directory already exists with different perissions the current code returns
an empty string.

The bsd variant of `ln` does not support the ``-T`` option.
Testing for existence using wildcard before creating new symlinks
should be sufficient here. Furthermore the target directory is
managed internally by this Makefile anyway.
