* Make the contract size limit configurable in the genesis config, making it possible to override milestone based configurations in a private network.

* Cancel the chain download via ChainDownloader.cancel instead of cancelling the future.
* Update SyncState when sync target changes in pipeline chain downloader.
* Use thenProcessAsyncOrdered
* Log chain download progress.
* Add a short delay after an error occurs before retrying.
* Replicate somewhat weird stop but don't be complete behaviour of EthTask chain downloader to get shutdown working properly.

Adds handling for options that need to be configurable for tuning and performance but in general are not long-term supported configuration options.
Options that are added via a mixin, are hidden, and that start with `--X` are considered 'Unstable Options.' These options do not show up via normal help facilities but are enumerated via a `XHelp` CLI invocation. These options are unstable, unsupported, and undocumented. They may be added, removed, or modified without prior warning or notice. Use them at your own risk.
For example, the `--Xrocksdb-max-open-files` flag can be set via CLI and can increase the number of max open files RocsDB uses. On a 8GB memory system the default is appropriate, but on a 128GB memory system a much larger number may improve performance. Normal operation scenarios will not need to modify this flag.

- add `--fast-sync-min-peers` hidden cli option
- add `--fast-sync-max-wait-time` hidden cli option
- update `FastSyncActions` to handle no timeout behaviour (when timeout set to 0 or no timeout set then we just trigger asynchronously the `waitPeersTask`)
- update unit tests mock related to sync config builder
- add fast sync options in `everything_config.toml` and `partial_config.toml`
- re enable PantheonCommandTest.syncModeOptionMustBeUsed
- add new flags in `noOverrideDefaultValuesIfKeyIsNotPresentInConfigFile` and `overrideDefaultValuesIfKeyIsPresentInConfigFile` tests

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).

* 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).
