Simplify --net ns: syntax?

[apostasie]

What is the problem you're trying to solve

Currently, we require absolute path to the ns.

eg:

sudo nerdctl run -d --net ns:/run/netns/lepton-test busybox sleep Inf

and (of course?)

sudo nerdctl run -d --net ns:lepton-test busybox sleep Inf

... will fail.

Is there a particular reason not to allow network namespaces names instead of full path?
Put otherwise: are there cases where passing along a full path that is not under /run/netns would be required?

Describe the solution you'd like

--net ns: should be compatible with Podman; so supporting absolute paths SGTM if Podman supports them
