vrfs attack Byzantine test

[rrrooommmaaa]

Add next integration test:

# 1. All nodes communicate honestly until round 10th
# 2. Lock notarization of round 10 in all nodes (block verification tickets sending)
# 3. The adversarial node sends VRF for round 11
# 4. All nodes receive adversarial node VRF for round 11, cache it and unblock the sending of pending verification tickets 
# 5. Verify whether the network continues operating correctly

Check the created integration test by running the next commands.

$ ./docker.local/bin/build.miners-integration-tests.sh && ./docker.local/bin/build.miners-integration-tests.sh

$ ./docker.local/bin/start.conductor.sh spam-miners

Although not used it also adds a directive to check whether a round was finalized.

What's the expected result of this test? Is this test to check whether the miners blacklist the spamming miner?

I couldn't also get the spamming mechanism. Are we considering the spam mechanism to be the miner forcing the existence of 2 uncompleted rounds?

[fabioDMFerreira]

@dabasov any other changes, you want me to do?

[sagchain]

@dabasov should we even track this? This has open without any activity since long.
