peer hooks -> events (#320) * peer hooks -> events * peerinfo -> peerid * include connection direction in event * check connection status after event * lock connmanager lookup also when dialling peer * clean up un-upgraded connection when upgrade fails * await peer eventing * remove join/lifetime future from peerinfo Peerinfo instances are not unique per peer so the lifetime future is misleading - it fires when a random connection is closed, not the "last" one * document switch values * naming * peerevent->conneevent

## A peer can be constructed in one of tree ways:
## 1) A local peer with a private key
## 2) A remote peer with a PeerID and it's public key stored
## in the ``id`` itself
## 3) A remote peer with a standalone public key, that isn't
## encoded in the ``id``
