There is no good way to recommend labels for podman container runlabel. Add the missing max-size log option. These are the only documented options so the completion should not suggest something different. Add proper --stop-signal completion. It will now complete all supported signal names both upper and lowercase depending on the user input. Also it work with and without the SIG prefix. Fixing the TODOs in this file are more complicated since they describe bigger features. [NO NEW TESTS NEEDED] Signed-off-by: Paul Holzinger <pholzing@redhat.com>
