There is a failure mode of IBFT whereby a validator fails to import
a block, and also fails to receive the NewBlock message from its
peers. This means said validator is unable to participate in
subsequent rounds, and may cause the network to halt.
To overcome this issue, if an IBFT validator receives messages from
a future height, it will update the "BestEstimatedHeight" of the
corresponding EthPeer object, such that the Synchroniser will
(eventually) download the requisite blocks - thus allowing the
IBFT network to continue to operate.

--> adapt `BlockBroadcaster` to use `send` method on `EthPeer`
--> adapt `EthProtocolMamnager` to utilize `BlockBroadcaster` to disseminate newly mined block

* Reduce ECIESHandshaker logging to trace since it documents a normal flow through the handshake process.

* Make the use of an existing fast sync state more explicit - passing it into the FastSyncDownloader.start method.
* Simplify FastSyncState constructors.
* Move PivotHeaderStorage to be FastSyncStateStorage and fully encapsulate loading and storing of FastSyncState instances.

Allow fast sync to resume if chain head is not genesis but a fast sync is still in progress.
If present, use the stored pivot block header when restarting.
Extract the fast sync logic out of DefaultSynchronizer into it's own class.

Modify EthScheduler to use shutdownNow immediately instead of trying shutdown first.
EthScheduler executes a lot of tasks which wait for responses from the network and may have a significant number of tasks queued. Using shutdown would wait for all network responses and all queued tasks to complete before exiting which almost always reaches the 2 minute timeout allowed before switching to shutdownNow. All tasks have to cope with being unexpectedly terminated (as would happen with a kill -9) so there's no reason to have this extra delay.

Return world states as an optional to allow code to handle world states not be available cleanly.
A world state is considered available if it's root node is available.
Delay storing the root hash when fast syncing a world state until the download completes so it isn't considered available and skip downloading world states that are already available.
