[Suggestion] Allow changing linux capabilities

[Double-0-seven7]

Is your feature request related to a problem? Please describe.
I tried to use the setcap command inside an ubuntu container without root permissions (without the --root option) to add more capabilities to a binary/app but it doesn't seem to do or change anything.
Describe the solution you'd like
allow me to add more capabilities to a binary inside a rootless container.
Describe alternatives you've considered
You can use podman manually to add/change linux capabilities but I dont really understand how to use it.
