Add a new tool called nm-in-vm to ease testing with virtual machines.
Some features cannot be tested from a container, like features that requires root access that we don't have in a rootless container. This tool will download and configure a virtual machine that will work in a very similar way than nm-in-container.
If no VM name is specified,
nm is used. If another name is specified, it can be configured and used in parallel. Different OS can be chosen: fedora, centosstream and debian *. Example
./nm-in-vm -v other-vm-name build debian-12.
To connect to a running VM, execute
./nm-in-vm [-v vm-name] [exec] or
./nm-in-vm --help for more complete info.
