Add Transaction Gossip Disable Test

[pcw109550]

This PR tests tx gossip disabling between two L2 execution clients. Requires #9.

Fixed op-erigon client's entrypoint.sh to disable tx gossiping by default. This is to follow op-geth's entrypoint.sh implementation.

op-geth:

EXTRA_FLAGS="--rollup.disabletxpoolgossip=true"

op-erigon(diff introduced in current PR):

if [ "$HIVE_OP_EXEC_DISABLE_TX_GOSSIP" != "" ]; then
    EXTRA_FLAGS="$EXTRA_FLAGS --rollup.disabletxpoolgossip=$HIVE_OP_EXEC_DISABLE_TX_GOSSIP"
else
    EXTRA_FLAGS="$EXTRA_FLAGS --rollup.disabletxpoolgossip=true"
fi

Example hive logs for new test:

created genesis files
added eth1 node 0 of type go-ethereum: 172.17.0.4
added op-l2 0: 172.17.0.5
added op-node 0: 172.17.0.6
added op-l2 1: 172.17.0.7
added op-node 1: 172.17.0.8
waiting for nodes to come up
peering execution clients 172.17.0.5 with 172.17.0.7
sent tx to verifier. Give some time to check tx gossiping is disabled
transaction not gossiped on sequencer
sent tx to sequencer. Give some time to check tx gossiping is disabled
transaction not gossiped on validator

Every test will fail on CI because --rollup.disabletxpoolgossip is not recognized because tx gossip disable implementation(testinprod-io/op-erigon#70) is not added in dockerhub docker image. Locally tested and works(l1ops, rpc, p2p). Will merge this PR after op-erigon remote docker image is updated.
