- Updated `wwctl upgrade` to handle updates - Maintained `.Container` and `.ContainerName` in tstruct - Added `ContainerName()` methods to node and profile objects - Added `--container`, `-C` aliases to wwctl commands (`<node|profile> <add|set>`) - Added `wwctl container` alias - Added support for `container_exit.sh` if `image_exit.sh` is not found Signed-off-by: Jonathon Anderson <janderson@ciq.com>
