* Backward Sync is now remembering recent finalized blocks.
When syncing using BWS we now consider finalized blocks reported by consensus layer.
When no finalized block is specified, nothing strange will go on. When Finalized block is specified
But Besu is not aware of any finalized block yet, we will sync as usual until the finalized block is about to get imported.
A new invariant is introduced when importing blocks using BWS.
All imported blocks has to descent from latest finalized block or a TTD block if we did not finalize yet.
* Importing a finalized block updates the information in Besu Mutable Blockchain.
* It is no longer possible to import blocks into the blockchain below a previously finalized block when using BWS
* When a new finalized block gets announced while BWS is in progress and Besu already has it imported, the Mutable Blockchain gets updated, and the chain gets checked for possible pruning
* When trying to import blocks of equal height as newly announced finalized block, then only the new announced finalized block will be possible to import using BWS
* When importing a new block using BWS after finalized, we can now guarantee that the block descends from latest finalized block

Add a new way to synchronize which is X_CHECKPOINT. This mode is experimental so use it at your own risk. This mode allows you to do like a snapsync but starting from a specific checkpoint instead of starting from the genesis.
This checkpoint will be in the genesis configuration of each network. To add the checkpoint mechanism in a network you just have to add the checkpoint section in the genesis.
Currently there is a checkpoint for ropten, goerli and mainnet.
Mainnet on i3.2xlarge <6 hours
Goerli on i3.2xlarge <1 hours

Upgrade errorprone to 2.13.1. Like all errorprone upgrades there are
new checks requiring code changes.

* Effectively constant booleans must now be returned as true/false.
* longs should not auto-cast to double.

Change the unit test execution to use the Junit5 JUnitPlatform. This
allows for a mix of junit 4 and junit 5 tests and for a gradual
migration to junit 5 instead of a big bang. One class depended on
junit 4 exceptions and was updated. Two tests depending on
native libraries fail gracefully on mac (and only mac).

The currently way Besu has to spot if a transaction has already been process, is to look if the transaction is present in the transaction pool, that by default is 4K, while the amount of pending transactions on the mainnet, is much more, the order of hundred of thousands, so basically even if a transaction has been already processed, the chances that it gets reprocessed is very high, with the result of doing a lot of useless work, that affects Besu performance.
A trivial solution could be to just raise the transaction pool size, but that is not always advisable, because it is critical for block production to keep it fast, and incresing its size could negatively affect the perfomance of the strategy choosen to select transactions to include in the block.
A better option, implemented here, is to leverage data that we already have, and that keeps the history of the transactions exchanged with other peers. This data is just a collection of transaction hashes that we have received or seen, and in any case if a transaction is in that collection, it means that it has already been processed by Besu, so it is possible to directly skip it.

Currently Besu has a limited support for sending NewPooledTransactionHashes messages, and other aspect related to reduce transactions synchronization traffic, described in the Ethereum Wire Protocol version 66.
Specifically:
Besu only uses NewPooledTransactionHashes for new local transactions, while it could be extended to any transaction added to the transaction pool
Besu does not limit the sending of the full transaction messages to a small fraction of the connected peers, and sends the new transaction hashes to all the remaining peers
This PR, extends eth/66 support and does some code refactoring, to remove some reduntant code and rename some classes to identify they are related to the NewPooledTransactionHashes message.
The main changes are:
Do not have a separate tracker for transaction hashes, since for them we can reuse PeerTransactionTracker, that tracks full transactions exchange history and sending queue with a peer. So PeerPendingTransactionTracker has been removed. --tx-pool-hashes-max-size is now deprecated and has no more effect and it will be removed in a future release.
When a new peer connects, if it support eth/6[56] then we send all the transaction hashes we have in the pool, otherwise we send the full transactions.
When new transactions are added to the pool, we send full transactions to peers without eth/6[56] support, or to a small fractions of all peers, and then we send only transaction hashes to the remaining peer that support eth/6[56]. Both transactions and transaction hashes are only sent if not already exchanged with that specific peer.

* Tune transaction worker queue capacity to adapt to mainnet
Currently Besu handles hundreds of transaction message per seconds,
so having a queue of 1M messages result in a lot of expired messages,
make sense to reduce the capacity to drop incoming messages that could not
be handled anyway.

* Tune the number transactions seen by peer to adapt to mainnet traffic
Currently on mainnet there are many thousand of pending transactions
exchanged between peers, but Besu has a short memory of what has been
exchanged with a specific peer, with the result that the same transaction
is often exchanged back and forth with the same peer, expecially when the
peer is another Besu.
