protocols/kad: Implement NetworkBehaviour::inject_address_change (#1649)

Browse Source 
With 826f513 a `StreamMuxer` can notify that the address of a remote
peer changed. This is needed to support the transport protocol QUIC as
remotes can change their IP addresses within the lifetime of a single
connection.

This commit implements the `NetworkBehaviour::inject_address_change`
handler to update the Kademlia routing table accordingly.
