container stop: release lock before calling the runtime
Podman defers stopping the container to the runtime, which can take some time. Keeping the lock while waiting for the runtime to complete the stop procedure, prevents other commands from acquiring the lock as shown in #8501. To improve the user experience, release the lock before invoking the runtime, and re-acquire the lock when the runtime is finished. Also introduce an intermediate "stopping" to properly distinguish from "stopped" containers etc. Fixes: #8501 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
