New flags in a `podman update` can change the configuration of HealthCheck when the container is started, without having to restart or recreate the container. This can help determine why a given container suddenly started failing HealthCheck without interfering with the services it provides. For example, reconfigure HealthCheck to keep logs longer than the usual last X results, store logs to other destinations, etc. Fixes: https://issues.redhat.com/browse/RHEL-60561 Signed-off-by: Jan Rodák <hony.com@seznam.cz>
