Address Manager should be responsible for create/update self peer record

[vasco-santos]

The AddressManager should be responsible both for creating and updating the self peer record over time, as listen addresses or announce/nonAnnounce are updated.

This functionality currently lives on the TransportManager, which should only be responsible for the listeningAddresses.

The AddressManager should also be responsible for tracking the peer's observed addresses.
