Support same dataId with different group and namespace can't override in local

[steverao]

Background

Spring Boot 2.4 introduced a new way to import configuration data via the spring.config.import property.
But in local environment, if we add following properties in application.yml:

spring:
  config:
    import:
      - optional:nacos:test2.yml?group=DEFAULT_GROUP&refreshEnabled=true
      - optional:nacos:test2.yml?group=test&refreshEnabled=true

The one will override another. For specific reason, that is because we create propertySource name by dataId, we should construct the name by dataId@group@namespace.

How to do

You can refer to spring-cloud-starter-alibaba-nacos-config module in branch of 2021.x and understand how we pull config from config center by spring.config.import.

Maybe it is better to align with Nacos format : group + "@@" + dataId
