Add a new [device*] section to NetworkManager.conf. This works similar like the default connection settings in [connection*]. This will allow us to express per-device configuration in NetworkManager.conf in our familar style. Later, via NMConfig's write API it will be possible to make settings accessible via D-Bus and persist them in NetworkManager-intern.conf. This way, the user can both edit configuration snippets and modify them via D-Bus, and also support installing default configuration from the package. In a way, a [device*] setting is similar to networkd's link files. The match options is all encoded in the match-device specs. One difference is, that the resulting setting can be merged together by multiple section by partially overwriting them. This makes it more flexible and allows for example to drop a configuration snippet that only sets one property, while the rest can be merged from different snippets.
