Sentinel

Is your feature request related to a problem? Please describe.

I'm looking for a replacement for hystrix, after try sentinel with feign, i found is feign resource name defination way is wired.
SentinelInvocationHandler.java 102~103
String resourceName = methodMetadata.template().method().toUpperCase() + ":" + hardCodedTarget.url() + methodMetadata.template().path();
it's hard code, when i want a consist config with different environment, urls are not same, so i must use different configuration for each environment. WTF of this hard code done?

Describe the solution you'd like

I prefer to use MethodMetadata#configKey property, which is smooth compatible with hystrix.

Describe alternatives you've considered

Or just extract with a resourceNameBuild() method, let user control the config.

Additional context

If provide a annotation config way is better.
