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.

A pause container is added to the pod if the user opts in. The default pause image and command can be overridden. Pause containers are ignored in ps unless the -a option is present. Pod inspect and pod ps show shared namespaces and pause container. A pause container can't be removed with podman rm, and a pod can be removed if it only has a pause container.

Do not set any hostname value in the OCI configuration when --uts=host
is used and the user didn't specify any value. This prevents an error
from the OCI runtime as it cannot set the hostname without a new UTS
namespace.
Differently, the HOSTNAME environment variable is always set. When
--uts=host is used, HOSTNAME gets the value from the host.

We should not be using the test systems registries.conf file for integration
tests. We should always use a constructed file created specifically for the
integration tests or we stand to have unpredictable results. The beforeTest
function now sets an environment variable pointing to a registries.conf file
in the test's tempdir. That file will container docker.io as a default.
The afterTest function then clears the environment variable.

Because our tests are getting so long, we want to be able to audit which tests are taking

actually get used.

Use github.com/containers/psgo instead of execing `ps (1)`. The psgo
library enables a much more flexible interface with respect to which
data to be printed (e.g., capabilities, seccomp mode, PID, PCPU, etc.)
while the output can be parsed reliably. The library does not use
ps (1) but parses /proc and /dev instead. To list the processes of a
given container, psgo will join the mount namespace of the given
container and extract all data from there.
Notice that this commit breaks compatibility with docker-top.

Bind all the specified TCP and UDP ports so that another process
