The NuDB database backend is a high performance key/value store presented as an alternative to RocksDB on Mac and Linux deployments, and the preferred backend option for Windows deployments. The LevelDB backend is deprecated for all platforms. This includes these changes: * Add Backend::verify API for doing consistency checks * Add Database::close so caller can catch exceptions * Improved Timing test for NodeStore creates a simulated workload
