feat(l1): add eth to enr

[mechanix97]

Motivation

The eth pair was not implemented in the current node record struct.

Using this information when trying to connect to a new peer, allow us to discard incompatible nodes faster

Description

The fork_id struct is constructed only once before the handling process starts

The eth pair contains a single element list, which is a ForkId element. It's encoded/decoded using the default RLP procedure.

When exchanging the ENRrequest/ENRresponse messages the eth pair is included

It can be tested starting a new node with debug level:

cargo run --bin ethrex -- --network test_data/genesis-kurtosis.json --log.level=debug

And connecting a new peer using the following command:

cargo run --bin ethrex -- \
--network ./test_data/genesis-kurtosis.json \
--bootnodes=$(curl -s http://localhost:8545 \
-X POST \
-H "Content-Type: application/json" \
--data '{"jsonrpc":"2.0","method":"admin_nodeInfo","params":[],"id":1}' \
| jq -r '.result.enode') \
--datadir=ethrex_c \
--authrpc.port=8553 \
--http.port=8547 \
--p2p.port=30388 \
--discovery.port=30310

A debug msg can be seen once the eth pair is validated
