Add Experimental QUIC support (#4577)

## Issue Addressed

#4402 

## Proposed Changes

This PR adds QUIC support to Lighthouse. As this is not officially spec'd this will only work between lighthouse <-> lighthouse connections. We attempt a QUIC connection (if the node advertises it) and if it fails we fallback to TCP. 

This should be a backwards compatible modification. We want to test this functionality on live networks to observe any improvements in bandwidth/latency.

NOTE: This also removes the websockets transport as I believe no one is really using it. It should be mentioned in our release however.
