Currently, firewalld has a "panic mode" which, as you might expect,
drops everything. It seems reasonable for it to also have a "open for
testing" mode which would temporarily let everything through. The
advantage over stopping and restarting is that any
dynamically-generated rules could persist (for example, you wouldn't
break networking in your VMs).
