Adds metrics to expose:
* height of best known block
* synchronizer in sync flag
* max peers
* Timestamp of current chain head

* It returns for any block we would broadcast to other peers, when
we would broadcast them.
* It returns a JSON String containing hash, number, and timestamp
* This event data is not set in stone, it may change in type or content.
* Acceptance tests and unit tests got a re-work away from the assumption
that there is only one plugin type.

Reduce the amount of work done within synchronized blocks in PendingTransactions.
In particular getTransactionByHash and notifying listeners of added or removed transactions are no longer in synchronized blocks.

* Bail out of addRemoteTransactions immediately if we're not in sync instead of after we sort by nonce and begin iterating.
* Don't sort transactions by nonce. This was only required because we previously rejected transactions where the nonce was too high.

* Don't copy collections if we don't need to. Change types higher up if needed.
* Don't use Guava's Object.equal, use Java's Objects.equals.
** add errorprone test to enforce the banning of Guava's Objects class.

* Change all Stream<?> getX() and Stream<?> x() methods to Stream<?> streanX methods, such as `Stream<Peer> streamIdlePeers()`
* Update coding conventions to reflect this.

Replaces the RocksDB based queue for pending world state download tasks with one that uses a simple file. Added tasks are appended to the file while the reader starts from the beginning of the file and reads forwards.
Periodically a new file is started to limit the disk space used. The reader deletes files it has completed reading.

Fix non-deterministic test caused by variable size of generated transactions.
Validate transactions against a size range rather than a fixed size
* Use assertj instead of own method.

Provides better control over the maximum number of concurrent requests to a peer.
Gives a fairer allocation of peers to requests being made.
Avoids a task failing because all peers are busy which then introduces a delay before the request is retried.

Store the header for the current chain head and total difficulty to avoid RocksDB lookups when requesting those common values.
Also uses that cache to avoid a database lookup when checking if a block has already been imported if the block's parent is the current chain head.
