[Enhancement] Extract the interval of fetchNameServerAddr

[lizhimins]

Before Creating the Enhancement Request

• I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Summary

The task of the Broker to discover the NameServer is performed by BrokerOuterAPI#fetchNameServerAddr at an interval of 2 minutes. The registration interval in BrokerController#registerBrokerAll is 10 seconds.

If the address of the NameServer changes, the Broker may not be able to discover the new NameServer and register with it in a timely manner. It is suggested to extract the interval of fetchNameServerAddr as a parameter for the Broker.

Motivation

The task of the Broker to discover the NameServer is performed by BrokerOuterAPI#fetchNameServerAddr at an interval of 2 minutes. The registration interval in BrokerController#registerBrokerAll is 10 seconds.
