Add smb share feature for Chuangmi Camera (#1482)

The Xiaomi App have limitation in setting NAS location, it has to be in
the local network. It discover the NAS then list them then let me
choose. I have a NAS across the VPN and actually it's accessible, but
not able to be discovered and set.
This function can help people config NAS outside the local network.

Example:
```shell
miiocli chuangmicamera --ip 192.168.60.11 --token xxxxxxxxxx set_nas_config on "smb://user:pass@192.168.40.2/camera" realtime quarter
```

If the `share` param left empty, It will keep the last config.

Tested on `chuangmi.camera.ipc013`
