Retry on bad dogstatsd connection (#13091)
- Introduce a new telemetry configurable parameter retry_failed_connection. User can set the value to true to let consul agent continue its start process on failed connection to datadog server. When set to false, agent will stop on failed start. The default behavior is true.
