The OCI runtime might use the cgroups to see what PIDs
are inside the container, but that doesn't work with rootless
containers.

Manage the case where the main process of the container creates and
joins a new user namespace.
In this case we want to join only the first child in the new
hierarchy, which is the user namespace that was used to create the
container.

We cannot re-exec into a new user namespace to gain privileges and
access an existing as the new namespace is not the owner of the
existing container.
"unshare" is used to join the user namespace of the target container.
The current implementation assumes that the main process of the
container didn't create a new user namespace.
Since in the setup phase we are not running with euid=0, we must skip
the setup for containers/storage.

Because our tests are getting so long, we want to be able to audit which tests are taking
the longest to complete. This may indicate a bad test, bad CI, bad code, etc and therefore
should be auditable.
Also, make speed improvements to tests by making sure we only unpack caches images that
actually get used.

Most images won't work without multiple ids/gids. Error out
immediately if there are no multiple ids available.
The error code when the user is not present in /etc/sub{g,u}id looks
like:
$ bin/podman run --rm -ti alpine echo hello
ERRO[0000] No subuid ranges found for user "gscrivano"
