Make sure to look for the container's exit code when it's in stopped
state. With `--restart=always`, the container seems to stay in the
stopped state which led the wait logic to loop until the 20 seconds
timeout for the cleanup process to have finished kicks in.
Also defensively make sure to loop when the container is in stopped
state but no exit code has been written yet.
Add a regression test to make sure Podman doesn't wait more than 20
seconds. Even on a CI machine under high load I expect it to take much
much much less than that, so I do not expect this test to flake in the
future.

In the recent past, I met the frequent need to wait for a container to
exist that, at the same time, may get removed (e.g., system tests in [1]).
Add an `--ignore` option to podman-wait which will ignore errors when a
specified container is missing and mark its exit code as -1. Also
remove ID fields from the WaitReport. It is actually not used by
callers and removing it makes the code simpler and faster.
Once merged, we can go over the tests and simplify them.
