Make the PeerManager and CrowdPeerManager abstract to ensure that a failure to

bind something to PeerManager.class will result in initialization failure.

A system that uses the peer services needs to extend PeerManager or
CrowdPeerManager with a concrete PeerManager and then
bind(PeerManager.class).to(SomePeerManager.class) to properly satisfy the
dependency.
