when doing localized tests (not varlink), we can use secondary image
stores as read-only image caches. this cuts down on test time
significantly because each test does not need to restore the images from
a tarball anymore.

Fallback to executing ps(1) in case we hit an unknown psgo descriptor.
This ensures backwards compatibility with docker-top, which was purely
ps(1) driven.
Also support comma-separated descriptors as input.

a series of improvements to our ginkgo test framework so we can
get better ideas of whats going on when run in CI

We have little to no testing to make sure we don't break podman image and
podman container commands that wrap traditional commands.
This PR adds tests for each of the commands.

Add the ability to run the integration (ginkgo) suite using
the remote client.
Only the images_test.go file is run right now; all the rest are
isolated with a // +build !remotelinux. As more content is
developed for the remote client, we can unblock the files and
just block single tests as needed.

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.

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.

Make the output of top tabular to be compatible with Docker. Please
note, that any user-input for `GetContainerPidInformation(...)` will be
ignored until we have found a way to generically and reliably parse ps-1
output or until there is a go-lib to extract all the data from /proc in
a ps-1 compatible fashion.

As Matt pointed out, when running sleep in a container, the clean up was taking a
full ten seconds to stop container because sleep does not catch SIGTERM which is
the default podman stop signal and it had to wait for SIGKILL. Changing sleep to
top should result in better test times.

Due to the way ps arguments work, it was possible to display pids
that dont below to the container in top output. We now filter pids
that dont belong to the container out of the output. This also means
the pid column must be present in the output or we throw an error.

Issue #169 describes a common failure when running podman top where
if the commands inside the container container a space in them, podman
will panic. This was occuring because we take the output from ps and
attempt to format it nicely for output and things like JSON. Given that
this cannot be predicted or dealt with programatically, the decision was
made to deprecate the format switch and simply output what ps provides
us.
Migrated top integration tests to ginkgo.
