[RFC] OpenSergo fault-tolerance spec v1alpha1 proposal | 流控降级与容错标准 v1alpha1 about opensergo-specification HOT 6 OPEN

apiVersion: fault-tolerance.opensergo.io/v1alpha1
kind: FaultToleranceRule
metadata:
  name: my-rule
  namespace: prod
  labels:
    app: my-app # 规则配置生效的应用名

建议将匹配生效应用名部分(app: my-app)放到spec中，例如.spec.selector或者.spec.selector. matchLabels。

意义：

1. metadata部分应当只用于设置当前CR(容错治理规则)的元数据；
2. 保持和其他CRD规范的语义一致，避免产生歧义，易于使用--例如Istio中的Gateway，k8s中的Deployment；

@YunWZ Good idea. Would you like to contribute a PR to improve it?

Of course

I'm confused about there parts:

1. What is kind of HttpRequestFallbackAction. In the sentinel go document, there are only five type of rules, RateLimitStrategy、ThrottlingStrategy、ConcurrencyLimitStrategy、CircuitBreakerStrategy、AdaptiveOverloadProtectionStrategy. How can we declare such a type?
2. limitMode is not implemented in the current code, right? For example, in ConcurrencyLimit, use isolation to generate a rule. But in this rule, it doesn't have limitMode attribute.
3. The slowConditions field also does not exist in currently code, right?

@halfrost For 1, you may refer to the structure of FaultToleranceRule. HttpRequestFallbackAction is a kind of FallbackAction (not a Strategy), which describes the fallback HTTP response when the associated strategies are triggered.

For 2 and 3, which code repo are you referring to? These fields have been already defined in https://github.com/opensergo/opensergo-java-sdk/blob/main/src/main/proto/fault_tolerance/v1/fault_tolerance.proto

@sczyh30 For 2 and 3, I didn't find these 2 attribute fields in sentinel-go's code.
