Accept domain name and ip addresses for peers

[sandreae]

We want to be able to pass addresses for direct peers and relay peers into aquadoggo as both ip addresses and domain names. This PR implements parsing either addresses in string format to a SocketAddr using ToSocketAddrs and then constructs a Multiaddr in the format libp2p expects.

Addresses for relay and direct peers are now accepted in the following formats:

• ip address: 123.123.123:2022
• domain name: welle.liebechaos.org:2022

I was under the impression that libp2p would do this lookup for us under the hood, but even after many attempts I couldn't get it to work, so I switched to this method which is preferable in my opinion anyway.
