Routing rules are unlike addresses or routes not tied to an interface. NetworkManager thinks in terms of connection profiles. That works well for addresses and routes, as one profile configures addresses and routes for one device. For example, when activating a profile on a device, the configuration does not interfere with the addresses/routes of other devices. That is not the case for routing rules, which are global, netns-wide entities. When one connection profile specifies rules, then this per-device configuration must be merged with the global configuration. And when a device disconnects later, the rules must be removed. Add a new NMPRulesManager API to track/untrack routing rules. Devices can register/add there the routing rules they require. And the sync method will apply the configuration. This is be implemented on top of NMPlatform's caching API.
