Support Clique PoA

[avenbreaks]

Describe the feature

Does reth currently support building clique consensus-based networks like goerli?

Examples run :

reth init --datadir=/datareth --chain=genesis.json

reth node \
    --datadir=/workspace/reth/datareth \
    --chain=/workspace/reth/bin/scripts/genesis.json \
    --http \
    --http.port=8545 \
    --http.addr=0.0.0.0 \
    --http.corsdomain=* \
    --http.api=admin,debug,eth,net,trace,txpool,web3,rpc,reth,ots \
    --ws \
    --ws.addr=0.0.0.0 \
    --ws.port=8546 \
    --ws.api=admin,debug,eth,net,trace,txpool,web3,rpc,reth,ots \
    --ws.origins=* \
    --discovery.port=30303 \
    --port=30303 \
    --identity=poa-testnet \
    --authrpc.port=8551 \
    --authrpc.jwtsecret=/workspace/reth/bin/scripts/jwt.hex \
    --authrpc.addr=0.0.0.0 \
    --metrics=0.0.0.0:9001 \
    --log.stdout.format=terminal \
    --log.file.filter=info

clique is also being removed from geth because goerli is deprecated, there are no plans for this
