Refined network management (#1672)

This PR implements several refinements to the way that NetworkManager
controls the network interface.

- The monitor detects and logs changes to the network address
- The monitor detects and logs changes to the connection and will
reinitialize the connection if needed
- Remove NetworkInterface.java class, which wasn't used anywhere
- Use java.net.NetworkInterface to get IP addresses for any interface
(device)
- Adds a metric for the current IP address (address on the currently
selected interface)
