Allow for adding/removing/changing labels on running containers through `podman container update`

[InfoSec812]

Feature request description

Here's my use case. I have Nextcloud AIO running and I have labels attached for configuring Traefik for a reverse proxy. When I initially deploy, I have the reverse proxy pointed at the nextcloud-aio-domaincheck container. After the initial configuration I need to change that to point to the nextcloud-aio-apache container. I would prefer to do this sort of label change without having to restart the nextcloud-aio-mastercontainer. Does this seem feasible/desireable?

Suggest potential solution

In the options for podman container update allow for adding/removing/modifying labels

Have you considered any alternatives?

Changing the Quadlet and restart the container is possible, but modifying the labels on a running container would be preferable.
