Make it possible to provide gNMI Subcription paths on MNE creation in CLI instead of fixed values
Description
During MNE creation, one can send paths which the controller then should subscribe to. Currently, this is just a fixed value and there's no way to provide different paths in the creation process via CLI. It should be possbile to provide the desired paths during this process via typing in the console or maybe also via text file. Not fully decided and free to implement either or both options
