In the recent past, I met the frequent need to wait for a container to exit 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.

Does this PR introduce a user-facing change?

Add a new --ignore option to podman-wait.

@containers/podman-maintainers PTAL

@edsantiago FYI - I think this can be a nice helper in the tests
