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.

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.

There is no need to keep entire blocks during import after they have
been imported. Keep just the hashes instead.

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

* 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.
