Nacos is not working properly in DOMAIN mode

[lexburner]

Describe the bug
nacos-client should retry when nacos-server runs in cluster mode, but after configuring the domain name for nacos-server, nacos will think it has only one address and will not retry again.

Expected behavior
nacos-client should retry more than one time when configuring the domain name for nacos-server.

nacos should support retry times configuration item for developers because only the developers themselves know the most suitable retry times.

Acutally behavior

only invoke one time when a domain address is configured, nacos-client will not retry when exception occurs.

version: all

from above picture, nacos should retry n times.
