Andrey Smirnov 5811f4dda1 feat: implement link (interface) controllers
The structure of the controllers is really similar to addresses and
routes:

* `LinkSpec` resource describes desired link state
* `LinkConfig` controller generates `LinkSpecs` based on machine
configuration and kernel cmdline
* `LinkMerge` controller merges multiple configuration sources into a
single `LinkSpec` paying attention to the config layer priority
* `LinkSpec` controller applies the specs to the kernel state

Controller `LinkStatus` (which was implemented before) watches the
kernel state and publishes current link status.
