Implementation currently gets as far as managing the sync target and downloading checkpoint headers.

Also increases the number of requests without progress before considering the download stalled.

* Number of metrics labels need to match up with constructor
* Number of labels must be consistant, so I split it into two metrics
* Also, naming best practices say that sum() and avg() of a metric
should be meaningful, separating into two metrics fixes that.
* fix style issues (finals, intellij warnings)
* Change NoOpMetrics to check label count.
* Cascading changes to support this in many support classes. Mostly places
we presumed all NoOpMetrics were equals.

* Added ability to subscribe to dropped transactions from the transaction pending pool.
Implemented subscription webservice to support this.
* Added metrics to the pending transactions, tracking the number of local and remote transactions in the pool.
* Converted listener management in pending transactions to use the Subscribers util object.

The 25% of maximum peers is fairly arbitrary but is deliberately above zero to ensure we contribute something to the overall network even while catching up.

When chain downloading, the SyncTargetManager continues to
attempt to download headers/blocks from the current syncTarget,
even if the system is "insync". This is due to the fact that
the "insync" check is only performed at initial peer selection,
rather than on each loop of the chain downloader.

This only happens when there are multiple chain downloads in progress so the common ancestor is above the last header we imported, but safety-first...

When receiving an AddPeer, or when loading the static-nodes.json file, pantheon
should not accept its own NodeID as a valid connection (however, this should not invalidate the static-nodes file).

Most peers discovered on the network only define a single UDP port and have no explicitly defined TCP port. At least some of these peers are listening on the TCP port matching the advertised UDP port so assume the ports are the same and attempt a connection.

When RemovePeer is invoked, the specified peer is removed from the "Maintained" connections in NettyP2p, and the connection to said peer is disconnected.
The peer is not added to the blacklist, on the premise that this behaviour will typically be used when peer-discovery is disabled, thus no future connection to the peer in question will be attempted (except via an AddPeer JSON RPC call).

* Synchronizer returns false if it is in sync
* expand RunnerTest to test eth_syncing behaviour

* Maintain a staticnodes.json
The staticnodes.json file resides in the pantheon data directory,
is parsed at startup to determine which peers can be connected
to (aside from bootnodes), and is updated whenever addPeer/removePeer
RPC is invoked.
This file is not updated when finding neighbour peers (ONLY on RPC
call).

Lower the log level of discovery connections to unreachable networks,
such as a box without IPv6 enabled connecting to an IPv6 peer.

Biggest change is that UnusedVariable and UnusedMethod went to WARN by
default. Since our build is a no warning build this means we either need
to turn them off or fix them. I mostly opted for the latter. Test code
was mostly fixed, unused loggers were deleted, and other shipped code
was mostly suppressed.
Two less noisy fixes to not use `SortedSet` and to use zero based
comparable results instead of -1, 0, and 1. Also a compiler nit in
errorprone was suppressed, per the description it won't affect us.

* Capture input and output metrics for each pipe rather than out input.
* Replace the batching processor with a BatchingReadPipe that wraps a normal pipe and creates batching on the fly.
Avoids needing an extra thread and synchronization overhead to create batches.
