Confusing `bcvk ephemeral run` default behaviour

[jlebon]

To the uninitiated, bcvk ephemeral run -K containers-storage:quay.io/fedora/fedora-bootc (i.e. without -d) just seems to hang. It's not clear that you're supposed to either use --console to get the serial console, or e.g. switch to another terminal to bcvk ephemeral ssh into it.

Hmm, perhaps --console should be implied when not using -d? Would be nice also to set up autologin (that seems related to #236).

It's intended to roughly match podman run; I'm not totally sure about connecting the console to the container stdio by default. Maybe we should.

Alternatively, we could just print some useful information. And if we detect we're on a tty, we might as well do something fancier. One thing I'd like to add is good qmp support, which is another thing one might want on the default console as an option.

Yeah that would help a lot I think.
