Call the shutdown task async to allow the BftProcessor CountDownLatch to complete.
Start the next coordinator only once the previous shutdown is complete.

When producing the next block, the previousBlockHeader.number + 1 needs to be used to query the transition forkSchedule.
This is because the list of validators associated with each forkSchedule may be a different set to the current block.
This commit changes the implementation for getValidatorsAfterBlock to support this and points getValidatorsAtHead at this implementation.
Note getValidatorsForBlock's forkSchedule query is unchanged since we have already mined the block at the point this is called (e.g. for RPCs qbft_getValidatorsBy...).
For TransactionValidatorProvider, we need to use the next block's contract address but still use the previous block's validators in the contract call itself.
Querying validators using afterBlock vs forBlock may yield different (blockNumber -> validatorAddresses) combinations when transitioning into CONTRACT mode.
There we also split TransactionValidatorProvider validatorCache into two caches.
Add special case to ForkingValidatorProvider (BlockValidatorProvider.hasValidatorOverridesForBlockNumber) to support transitioning to blockheader mode with some validator overrides. This might be needed if the current validator set loses quorum and we
are no longer able to vote new ones in.
New integration test cases for validatorselectionmode transitions:
- contract -> contract
- contract1 -> blockheader -> contract2
- contract1 -> blockheader with overridden validators -> contract2
Fixes https://github.com/hyperledger/besu/issues/2901

During the transition from contract mode to block header mode, when creating the extra data for a new block, we need to look ahead to the next block's voteProvider to obtain the nonEmpty one associated with the BlockValidatorProvider.
This only applies to ForkingValidatorProvider which is currently only used for QBFT. However, we don't want QBFT to know it's using a ForkingValidatorProvider. Therefore we need to implement getVoteProviderAfterBlock on the ValidatorProvider interface even though it's implementation is equivalent to getVoteProvider.

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.
