Add support for working within Network Address Translation (NAT) environments.
This adds a CLI flag `--nat-method` with two options, `NONE` (the default and
current behavior) and `UPNP.` `--nat-method` will affect what IP address and
ports are advertised via the P2P discovery and other APIs that report the
address and port for P2P actions.
`UPNP` is intended for a typical home or small office environment where a
wireless router or modem provides NAT isolation.

- Update SyncStatusNodePermissioningProvider to use URI (without discovery port) instead of EnodeURI to allow optimised permission checking of static nodes
- Add EnodeURL.toURIWithoutDiscoveryPort

Query params can be used to adjust the number of peers required and number of blocks tolerance to be considered in sync.

Previously was only set after callbacks were invoked, allowing additional messages to be sent while parts of the supporting infrastructure for the peer was being torn down.

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

* 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.

Move RocksDBStats to it's own module. This also brings metrics to
metrics:core since none of our other module have nested modules but
they have peer modules.

Only specify discovery port explicitly when the discovery port differs
from the listening port.

Because of deep issues sometimes we get duplicate Peers that differ
in small ways. Tweak the test to verify we get all of the peers
we are expecting and to be tolerant of quasi-duplicate peers.

* 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.
