Mbed OS will soon be changing directory structure to the below:

```
connectivity
├── netsocket
├── lorawan
│   ├── mbed_lib.json // nanostack-interface's mbed_lib.json
│   ├── lorastack
│   ├── tests
├── nanostack
├── cellular
├── ...

```

This PR is a part of a wider \connectivity refactoring and implements the above new directory structure for \lorawan.
