Fix the image-size calculations of system-df, where the shared size is
the actual shared size with other images (including children) and the
(total) size is the sum of the shared and unique size [1].
To calculate parent/child relations, make use of the recently added
layer tree which allows for quick (and cached!) calculations.
Break calculating image disk usages into the image runtime to a) access
the layer tree, and b) make the code easier to maintain and extend.

As error types are not preserved on the client side (due to marshaling),
we cannot use `errors.Cause(...)` and friends but, unfortunately, have
to fall back to looking for substring the error messages.
Change the error checks in remote run to do substring matches and fix
issue #7340.

Basically, we want to force the application in the container to
(iff the container was made with a terminal) redraw said terminal
immediately after an attach completes, so the fresh Attach
session will be able to see what's going on (e.g. will have a
shell prompt). Our current attach functions are unfortunately
geared more towards `podman run` than `podman attach` and will
start forwarding resize events *immediately* instead of waiting
until the attach session is alive (much safer for short-lived
`podman run` sessions, but broken for the `podman attach` case).
To avoid a major rewrite, let's just manually send a SIGWINCH
after attach succeeds to force a redraw.

Problem: if either of the two "podman network create" tests
fail, all subsequent retries will also fail because the
created network has not been cleaned up (so "network create"
will fail with EEXIST).
Solution: run "podman network rm" as deferred cleanup instead
of in each test.
This is NOT a fix for #7583 - it is just a way to allow
ginkgo to retry a failing test.

- run tests: better "skip" message for docker-archive test;
remove FIXME, document that podman-remote doesn't support it
- run tests: instrument the --conmon-pidfile test in hopes
of tracking down flake #7580: cross-check pidfile against
output of 'podman inspect', and add some debug messages
that will only be seen on test failure.
- load tests: the pipe test: save and load a temporary tag,
not $IMAGE. Primary reason is because of #7371, in which
'podman load' assigns a new image ID (instead of preserving
the saved one). This messes with our image management, and
it turns out to be nonfixable.

To ensure that the user running in the container ahs a valid
entry in /etc/passwd so lookup functions for the current user
will not error, Podman previously began adding entries to the
passwd file. We did not, however, add entries to the group file,
and this created problems - our passwd entries included the group
the user is in, but said group might not exist. The solution is
to mirror our logic for /etc/passwd modifications to also edit
/etc/group in the container.
Unfortunately, this is not a catch-all solution. Our logic here
is only advanced enough to *add* to the group file - so if the
group already exists but we add a user not a part of it, we will
not modify that existing entry, and things remain inconsistent.
We can look into adding this later if we absolutely need to, but
it would involve adding significant complexity to this already
massively complicated function.
While we're here, address an edge case where Podman could add a
user or group whose UID overlapped with an existing user or
group.
Also, let's make users able to log into users we added. Instead
of generating user entries with an 'x' in the password field,
indicating they have an entry in /etc/shadow, generate a '*'
indicating the user has no password but can be logged into by
other means e.g. ssh key, su.

After attaching to a container, we wait for the container to finish and
return its exit code. Waiting for the container may not always succeed,
for instance, when the container has been force removed by another
process. In such case, we have to look at the *last* container-exit
event.
Also refactor the `ContainerRun` method a bit to return early on errors
and de-spaghetti the code.
Enable the remote-disabled system test.
