Must we use specific class here?

Purpose
Add the metrics display function to ucm_connector. You can specify which metrics to display on prometheus-grafana by configuring the metrics_configs.yaml file, and these metrics will also be output to the logs.
Modifications
Add three interfaces get_kv_connector_stats, build_kv_connector_stats and build_prom_metrics, as well as two classes UCMKVConnectorStats and UCMPromMetrics to ucm_connector.
Test
