We probably want to improve networkd's [Match] logic, to also work in
this case. I.e., to match on SSID. Not on my immediate TODO though,
but patches welcome ;-)

In general though, I quite like the idea of using networkd as a
glorified dhcp client. We probably still lack some features in
networkd before to make it support a bit of dynamic configuration
before this really makes sense though.
