Bug Description

At the time of writing the only way to add Udev rules is using the hw-assing tool and only to assign a specific device node to a module.

In many applications other udev rules are needed, e.g. ability to create symlinks to use self picked device name in snap and or source code, execute commands when a device is connected, etc.

Currently[1], oem snaps are able to add udev snippets to tag devices via the 'assign' yaml. It should be possible with hw-assign to resolve the symlink and tag the device in a similar manner.

Note: aiui, hw-assign is being reworked and there may be another mechanism in the future.
