Upgrade logs (#1495)

Browse Source 
## Issue Addressed

#1483 

## Proposed Changes

Upgrades the log to a critical if a listener fails. We are able to listen on many interfaces so a single instance is not critical. We should however gracefully shutdown the client if we have no listeners, although the client can still function solely on outgoing connections.

For now a critical is raised and I leave #1494 for more sophisticated handling of this. 

This also updates discv5 to handle errors of binding to a UDP socket such that lighthouse is now able to handle them.
