[ISSUE] When aliyun-rds-spring-boot-starter is integrated, the application cannot work

[m1ngyuan]

Describe the bug
When aliyun-rds-spring-boot-starter is integrated, the application cannot work

To Reproduce
Steps to reproduce the behavior:

在应用上集成了aliyun-rds-spring-boot-starter后台，应用在启用过程中会抛出duplicate endpoint operations异常，例如：Factory method 'jmxMBeanExporter' threw exception; nested exception is java.lang.IllegalStateException: Unable to map duplicate endpoint operations: [MBean call 'slow'] to rdsSlowEndpoint。
同样的情况发生在RdsErrorEndpoint、RdsPerformanceEndpoint、RdsSlowEndpoint,
为了能正常工作，我认为在这三个类中，只需要对方法进行重命名即可

Aliyun RDS spring boot starter background is integrated in the application. During the application enabling process, duplicate endpoint operations exception will be thrown, such as factory method 'jmxmbeanexport' thread exception; nested exception is java.lang.illegalstateexception: unable to map duplicate endpoint operations: [MBean call 'slow'] to rdsslowendpoint.
The same situation occurs in rdserrorendpoint, rdspermanceendpoint, rdsslowendpoint

In order to work properly, I think in these three classes, but the method needs to be renamed

Expected behavior
A clear and concise description of what you expected to happen.

RDS健康指标能正常输出

RDS health indicators can be output normally
