* 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

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).

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.
