Feature request: web socket connection between mev-relay and mev-geth

[thegostep]

Replacing the current eth_sendBundle HTTP-RPC endpoints on mev-geth with a web socket connection with the relay should help reduce latency.

Issue: flashbots/mev-geth#32

[thegostep]

v0.2 proposal

The use of RPC endpoints on mev-geth is replaced in v0.2 with a WebSocket connection which pulls blocks from a relay instead or receiving them via HTTP, this aims to reduce latency and improve node security by avoiding the need to open the rpc to the public.
