1. switches from a composable plugin model to a single-plugin model
2. switches class methods to static methods in the BaseConsensusRules class
3. adds create_transaction, sign_transaction, and verify_transaction to
the plugin API
TODO: If we adopt this model, all references in e.g. client.py to util
methods like `sign_tx` need to be routed through the plugin methods, and
possibly need to be added to the plugin interface.
Without this running blockchaindb yields:
