* [PAN-2786] Stop Transaction Pool Queue from Growing Unbounded
- use a `ArrayBlockingQueue` with a fixed size to limit the transaction task queue
- expose a method in `MonitoredExecutors` to create a working queue with a maximum capacity
- update `EthScheduler` to use a limited working queue for the `txWorkerExecutor`
* [PAN-2786] Implement a bounded timed queue
- implement a custom bounded queue
- use a time based policy with keep alive configuration
- implement eviction process based on the policy
- add metrics
* use field instead of parameter
* fix PR pass 1
- use concrete class instead of interface
- change metric name to comply with global policy
- update unit test
- wrap `Runnable` into `scheduleTxWorkerTask`
* fix PR
- remove time based policy
- use raw `Runnable`
- make a room for a new element at full capacity
* Update BoundedQueueTest.java
invert condition
* fix PR comments
- remove Mock class
- make logic more thread safe, avoid race condition
- remove element until the new one is accepted
* Update ethereum/eth/src/main/java/tech/pegasys/pantheon/ethereum/eth/manager/EthScheduler.java

* [PAN-2630] Synchronizer should disconnect the sync target peer on invalid block data
- check if headers are sequential
- if sequential, check if they form a chain, if not, disconnect the peer
* update behaviour and add tests
- change checks order
- add log message
- write tests
* disconnect sync target when InvalidBlockException
* remove power mockito
- remove powermockito
- write tests in subclasses of the `AbstractGetHeadersFromPeerTaskTest`
* fix Exception check bug
* fix PR discussion first pass
- add assertion to check when the peer is disconnected
- add assertion to check the peer has not been disonnected
- undo remove final on class
- remove sync target field
* remove spy invocation
* spotlessApply
* shouldDisconnectPeerIfInvalidBlockException

Adds metrics to expose:
* height of best known block
* synchronizer in sync flag
* max peers
* Timestamp of current chain head
Signed-off-by: Adrian Sutton <adrian.sutton@consensys.net>
* 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.
