Add incentivizing Lisk-BFT Protocol Participation

[shuse2]

Description

BFT module should expose a method which verifies if the BFT protocol is being followed as per LIP-0014

This method should be used when validating a block in order to validate the block reward. i.e. the block reward should be 25% of the current reward if the protocol is not followed. Blocks which doesn't follow this rule should be rejected.

This method should be used when creating a new block in order to use the correct block reward. i.e. new block which doesn't follow the protocol should be have its reward reduced to 25% of the current reward.

Motivation

Incentivize Lisk-BFT Protocol Participation

Acceptance Criteria

• Unit test the new method with all possible scenarios
