   In Dubbo 3.0.6, there is a log when empty provider happend.
   ```
   org.apache.dubbo.rpc.cluster.directory.AbstractDirectory#list
               logger.warn("No provider available after connectivity filter for the service " + getConsumerUrl().getServiceKey()
                   + " All validInvokers' size: " + validInvokers.size()
                   + " All routed invokers' size: " + routedResult.size()
                   + " All invokers' size: " + invokers.size()
                   + " from registry " + getUrl().getAddress()
                   + " on the consumer " + NetUtils.getLocalHost()
                   + " using the dubbo version " + Version.getVersion() + ".");
   ```
   All validInvokers means all of the invokers from registry except those unconnectable invokers.
   All routed invokers means all of the invokers being selected in routers.
   All invokers means all of the invokers from registry.
