Local Network Permission should be requested

To enforce privacy Google is introducing a new permission [Local Network Permission](https://developer.android.com/about/versions/16/behavior-changes-16#local-network-permission) that in future version will prevent us to make a `mDNS` query if not approved.

For now it is not yet released by Google but we can identify what it is going to change on our side and plan accordingly for the next release from them.
