Eliminate race condition on podman info
There is a potential of a race condition where a container is removed while podman is looking up information on the total containers. This can cause podman info to fail with an error "no such container". This change ignores the failure. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
