Do we have existing Prometheus implementation for Velox BaseStatsReporter?

[xumingming]

The BaseStatsReporter used in Prestissimo is a dummy implementation, do we have Prometheus implementation available?

presto/presto-native-execution/presto_cpp/main/PrestoMain.cpp

Lines 35 to 37 in 6222e07

	folly::Singleton<facebook::velox::BaseStatsReporter> reporter([]() {
	return new facebook::velox::DummyStatsReporter();
	});
