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.

This is the first step in supporting switchable consensus mechanisms.
Specifically this allows additional protocol specs to be inserted to the protocol schedule at milestones other than that explicitly specified in the genesis config.

This allows Besu to interop with an Quorum IBFT-1 network which has been updated to use a 2/3 validator threshold, rather than 2F+1.
Signed-off-by: Trent Mohay <trent.mohay@consensys.net>
When interop testing between Besu and Quorum, it was found
that Quorum's management of the ibft protocol had somewhat
changed, and resulted in besu failing to peer with Quorum
To overcome this, the version of the istanbul protocol in
Besu was upgraded to 99 (matching Quorum's).

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.

* Finish internal ConstantinopleFix->Petersburg transition, including
class names. Only backwards compatibility and retesteth use of the
name will remain.
* Remove four unused config fields from json configs. These are fields
with no code uses of any sort. All are implied by other fields.
eip150Hash, eip155Block, eip160Block, and daoForkSupport.
* Remove redundant fork block fields where their value is implied

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

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.

Aspects of the consensus mechanism associated with block creation, and validation have been moved
from the IBFT package, into into consensus/common, such that they can be reused for the QBFT
implementation.
