The Hash of a qbft payload is calculated by hashing the RLP'd bytes of the message-id, followed by the payload's encoded bytes.
RLP(msgCode, RLP(payload.encodedBytes()))

We were creating new in-memory storage segments each time we were
supposed to be retrieving it which prevented me from being able to test
what keys ended up being stored in that segment.

QBFT no longer validates all fields of the block header (eg nonce mixhash), as these have no bearing on the
safety model of the protocol.

Add QBFT rpc methods and namespace. At the moment, they are copied verbatim from IBFT namespace and may change in future once specifications are finalized.

All received QBFT messages are now validated with respect to protocol safety prior to be accepted to QBFT business logic.
This includes updates to the QBFT integration test framework.

This supplies the necessary validation logic for parsing received RoundChange messages.
This logic is wired into the QBFT business logic.

The code required to deserialise signed payloads for QBFT is verbose and can be reduced by templating.

Creates the validator for qbft commit messages, but does not wire it into business logic at this stage.

Adds the Prepare validator, but does not wire it into the QBFT message validation at this stage.

This adds the proposal and roundchange messages required for QBFT.
This does not wire in the ability to transmit/receive these messages, it just defines the message structure.

This adds the Prepare and Commit messages used in the QBFT protocol, this is an incremental movement toward QBFT - and does not offer new functionality.
