[Proposal] Make rule definition configurable

[y1yang0]

The current rule is hard-coded in the tool, and every time we add a new rule, we have to recompile the tool. Ideally, rules should be configurable, so that adding new rules does not require recompiling the entire project, and users can easily inject code into the functions they want.

Something like:

./otel-auto-instrumentation -config=rule.json 

{
    "rules":[{ "Function":"Do", "RecvType":"*Client","OnEnter":"onEnterDo","OnExit":"onExitDo"}]
}

再提个建议，业务代码是否支持注入埋点呢？我看现在 rule 都在 https://github.com/alibaba/opentelemetry-go-auto-instrumentation/blob/main/rule_enabler.go 文件中导入
