#### Why I did it Fix issue #16533 , telemetry service exit in master and 202305 branches due to no telemetry configs in redis DB. #### How I did it Enable default config if no TELEMETRY configs from redis DB. #### How to verify it After the fix, telemetry service would work with the following two scenarios: 1. With TELEMETRY config in redis DB, load service configs from DB. 2. No TELEMETRY config in redis DB, use default service configs.
