feat(CCHAIN-1193): Malicious node -- produce equivocations

[sergio-mena]

Closes: #1518

This PR introduces all kinds of equivocation. The behavior is hidden behind environment variable TEST_ONLY_MALICIOUS_NODE. This should NEVER be set in production.

The effect of this change is to produce all three types of equivocation in the network, where we can observe them in the logs, and RPC methods.

This PR will be reverted once the needed data has been produced on devnet

This was used to create a temporary malicious image to deploy on devnet. This has been done, so it's better for this code not to be merged to main
