Added functionality for users to transfer images from root storage to rootless storage without using sshd. This is
done through rootful podman by running `sudo podman image scp root@localhost::image user@localhost:: the user is needed
in order to find and use their uid/gid to exec a new process.
added necessary tests, and functions for this implementation. Created new image function Transfer so that
the underlying code is majorly removed from CLI

Address the TOCTOU when generating random names by having at most 10
attempts to assign a random name when creating a pod or container.
[NO TESTS NEEDED] since I do not know a way to force a conflict with
randomly generated names in a reasonable time frame.

There was the question about how long it takes to create a checkpoint.
CRIU already provides some statistics about how long it takes to create
a checkpoint and similar.
With this change the file 'stats-dump' is included in the checkpoint
archive and the tool checkpointctl can be used to display these
statistics:
./checkpointctl show -t /tmp/cp.tar --print-stats
Displaying container checkpoint data from /tmp/dump.tar

The OCICNI port format has one big problem: It does not support ranges.
So if a users forwards a range of 1k ports with podman run -p 1001-2000
we have to store each of the thousand ports individually as array element.
This bloats the db and makes the JSON encoding and decoding much slower.
In many places we already use a better port struct type which supports
ranges, e.g. `pkg/specgen` or the new network interface.
Because of this we have to do many runtime conversions between the two
port formats. If everything uses the new format we can skip the runtime
conversions.
This commit adds logic to replace all occurrences of the old format
with the new one. The database will automatically migrate the ports
to new format when the container config is read for the first time
after the update.
The `ParsePortMapping` function is `pkg/specgen/generate` has been
reworked to better work with the new format. The new logic is able
to deduplicate the given ports. This is necessary the ensure we
store them efficiently in the DB. The new code should also be more
performant than the old one.
To prove that the code is fast enough I added go benchmarks. Parsing
1 million ports took less than 0.5 seconds on my laptop.
Benchmark normalize PortMappings in specgen:
Please note that the 1 million ports are actually 20x 50k ranges
because we cannot have bigger ranges than 65535 ports.

[CI:DOCS] Fix swagger definition for the new mac address type

The new mac address type broke the api docs. While we could
successfully generate the swagger file it could not be viewed in a
browser.
The problem is that the swagger generation create two type definitions
with the name `HardwareAddr` and this pointed back to itself. Thus the
render process was stucked in an endless loop. To fix this manually
rename the new type to MacAddress and overwrite the types to string
because the json unmarshaller accepts the mac as string.

Fix rootless cni netns cleanup logic and rename to rootless netns

Since we want to use the rootless cni ns also for netavark we should
pick a more generic name. The name is now "rootless network namespace"
or short "rootless netns".
The rename might cause some issues after the update but when the
all containers are restarted or the host is rebooted it should work
correctly.

We should mount the full runtime directory into the namespace instead of
just the netns dir. This allows more use cases.

The check if cleanup is needed reads all container and checks if there
are running containers with bridge networking. If we do not find any we
have to cleanup the ns. However there was a problem with this because
the state is empty by default so the running check never worked.
Fortunately the was a second check which relies on the CNI files so we
still did cleanup anyway.
With netavark I noticed that this check is broken because the CNI files
were not present.
