This is to avoid alerting spam for errors from inside lapin library that we handle e.g. by reconnecting to RabbitMQ.

Depends on D13607

When Tunnelbroker is open, stop RabbitMQ server.

Before: Error was displayed with errorType = AMQP_ERROR that connection is lost.
After: The error is not displayed from this handler. Error message appears only when all exponential backoff attempts fail.
