Add an --ignore flag to podman rm and stop. When specified, Podman will
ignore "no such {container,pod}" errors that occur when a specified
container/pod is not present in the store (anymore). The motivation
behind adding this flag is to write more robust systemd services using
Podman. A user might have manually decided to remove a container/pod
which would lead to a failure during the `ExecStop` directive of a
systemd service referencing that container/pod.
